The Tutankhamun collection: a decade of stabilisation
When the Grand Egyptian Museum opened its Tutankhamun galleries to the public in phases between 2021 and 2024, the conservation team had been working for nearly a decade to make it possible. Approximately five thousand objects from the tomb of the boy king — discovered by Howard Carter in 1922 — required individual condition assessments before they could be safely moved from the Egyptian Museum in Tahrir, where many had sat in storage for decades under conditions that had caused slow, cumulative damage.
The GEM's conservation centre, built as a working laboratory visible to visitors, handled the most fragile pieces in-house. The gilded wooden shrine from the antechamber — one of four nested shrines that once encased Tutankhamun's sarcophagi — was among the most demanding treatments. Its surface gilding had lifted in hundreds of places, and the underlying wood had warped in the humidity of the old museum's stores. Conservators at GEM spent fourteen months consolidating the gilding with Japanese tissue paper and a dilute reversible adhesive before the shrine could be moved. The techniques are documented in the GEM conservation register, portions of which the institution has made available to researchers.
The chariot assemblage — six chariots in varying states of preservation — presented different challenges. Wood, leather, gold overlay and textile elements all respond differently to environmental changes. The two state chariots were treated in a purpose-built chamber that maintained a stable 45% relative humidity throughout consolidation, which took eleven months. Organic material as old as three thousand years does not tolerate rapid humidity swings; even moving a treated object from the laboratory to the gallery requires careful transit protocols, including sealed crates with buffering material.
The objects are now displayed across twelve galleries in the museum's southern wing. The conservation team continues to monitor humidity, temperature and light levels in each gallery, adjusting the environmental controls seasonally. Not everything is finished: several hundred objects from the original Carter discovery remain in conservation queues, and new examination of previously untreated pieces continues each season. The GEM's publicly stated goal is to have the complete documented collection available for scholarly access by 2028, even if not all pieces are on public display.
The Khufu Solar Boat: relocation as restoration
The first Khufu Solar Boat — a dismantled cedarwood vessel discovered in 1954 in a limestone pit at the foot of the Great Pyramid — was reconstructed and displayed in a purpose-built museum on the Giza plateau for decades. That building, opened in 1982, was not designed for the long-term conservation of ancient wood. By the 2010s, the climate inside had become difficult to control, and the structure itself had deteriorated to the point where it posed risks both to the boat and to visitors.
The decision to relocate the reassembled boat to the Grand Egyptian Museum was taken in consultation with the Supreme Council of Antiquities and a team of Japanese specialists — Japan had led the original 1980s reconstruction project. The relocation required disassembling the boat into its 1,224 component planks and timbers, documenting each piece photographically and by 3D scan, treating any newly identified surface instability, and then reassembling the vessel within a specially designed hall at GEM.
The new Boat Hall opened in late 2021. Its environmental systems are a significant improvement on the old site: a precise climate-control installation holds temperature at 19°C and relative humidity at 50%, within tolerances that wood of this age and previous treatment history requires. The hall is also sealed from the main visitor circulation, with viewing through a full-height glazed screen, which limits the humidity load that large numbers of visitors would otherwise introduce. A second Khufu boat — discovered in an adjacent pit in 1987 and left sealed until recently — is being evaluated for eventual relocation and display.
Journalists and conservators following the relocation project noted that it demonstrated something straightforward in theory but difficult in practice: that an existing restored object can require as much conservation intervention as a freshly excavated one. In the process of disassembly, technicians found areas of previous adhesive treatment from the 1980s that were incompatible with the current approach and had to be carefully reversed before the new relocation work could proceed.
The Great Sphinx: structural consolidation, phase by phase
The Great Sphinx at Giza is among the most heavily treated ancient monuments in the world — a record that is not always flattering. Earlier interventions in the twentieth century, some using Portland cement, had inadvertently accelerated the erosion they aimed to stop by trapping moisture and creating differential stress in the limestone body. The Egyptian Antiquities Authority and its successor bodies have been working since the 1980s to undo the worst of those earlier repairs while simultaneously addressing ongoing weathering.
Phase I and Phase II of the current structural programme, completed in 2009 and 2023 respectively, concentrated on the southern flank of the monument, where a combination of rising groundwater, salt crystallisation and wind erosion had left surface layers unstable. The treatment methodology adopted natural hydraulic lime — broadly compatible with the original limestone — applied in small consolidation plugs that can be removed if better techniques become available. This is the reversibility principle applied at monumental scale.
Phase III, currently under way, addresses the northern flank and the base enclosure walls. The work involves surface cleaning to remove salt crusts that form when groundwater rises, micro-injection of lime-based grout into open fissures, and the insertion of stainless-steel dowels where large limestone blocks have separated. All treatments are documented by photogrammetric survey before and after each intervention, building a spatial record that conservators intend to be useful for the next phase, whenever it occurs.
The Sphinx is not a museum object, but its treatment programme has direct implications for museum conservation practice: the techniques refined on monumental limestone at Giza feed directly into how conservators handle limestone objects and architectural elements in the galleries at the Egyptian Museum and the GEM. For a detailed account of the technical vocabulary behind these choices, see our conservation methods coverage.
The Royal Mummies Hall: transfer and redisplay
In April 2021, twenty-two royal mummies — eighteen kings and four queens from the New Kingdom, spanning rulers from Seqenenre Tao to Ramesses IX — were transferred from the Egyptian Museum in Tahrir to the National Museum of Egyptian Civilisation in Fustat, Old Cairo. The transfer, which involved a ceremonial motorcade through central Cairo that attracted global attention, was preceded by approximately eighteen months of conservation preparation that received far less coverage.
Each mummy required a detailed condition assessment by the conservation team. X-ray and CT scanning was conducted on all twenty-two individuals, providing the most comprehensive radiological dataset ever assembled for the royal collection. The imaging revealed previously undocumented healed fractures, surgical interventions from ancient embalmers, and areas of internal instability in the linen wrappings that could not be seen externally. Several mummies required consolidation of fragile wrapping layers before they could safely undergo the vibrations of road transport.
The NMEC display cases are purpose-built for the collection, with sealed micro-environments inside each vitrine maintaining humidity at levels matched to the condition of each individual mummy. The hall itself operates at a higher humidity than a standard gallery to protect the linen and organic materials. Oxygen levels inside the cases are monitored remotely. At the time of publication, the hall is open to the public and represents one of the most technically sophisticated mummy display environments in any museum worldwide.
The question of where the mummies will remain long-term is subject to ongoing institutional discussion. The Egyptian Museum Tahrir is due for a major refurbishment in the coming decade; the NMEC display was conceived as a permanent installation, but permanent in heritage terms always means "subject to revision when circumstances change." For coverage of what else the NMEC now shows, see our current exhibitions page.
Saqqara: finds, consolidation and the challenge of quantity
The Saqqara necropolis, the burial ground for Memphis spanning at least three thousand years of Egyptian history, has been the site of some of the most significant recent discoveries in Egyptian archaeology — and, consequently, some of the most demanding conservation challenges. Seasons between 2018 and 2026 have yielded sealed shafts containing complete Late Period coffin sets, New Kingdom mummies with intact gilding, and Ptolemaic bronzes in quantities that have outpaced the capacity of available laboratory space more than once.
The 2020 discovery of approximately one hundred and thirty intact Late Period coffins in three sealed shafts near the Step Pyramid complex brought international attention, but the conservation reality was less photogenic than the press images suggested. The coffins were in good structural condition — the shafts were dry and undisturbed — but the volume of objects requiring individual assessment, photographic documentation, surface stabilisation and safe storage before any could be moved to a museum created a logistical challenge that took the Egyptian team, working with international partners, the better part of two seasons to work through.
The 2022 and 2023 seasons at a deeper excavation near the Bubasteion cliff added New Kingdom material to the queue: gilded mummy masks in fragile condition, wooden coffins with flaking painted decoration, and textile wrappings that had begun to lose structural integrity when the burial environment was disturbed by excavation. The Saqqara conservation team now operates a field laboratory on site during excavation seasons, which has reduced the risk of damage during the critical window between discovery and proper storage.
Some of the Saqqara material has entered museum display already — a selection of the 2020 coffins is now at the GEM — while other pieces remain in conservation storage at the site or at the Egyptian Museum's restoration centre. The flow of objects from Saqqara into institutional collections is likely to continue for years, given the scale of the necropolis and the pace of current excavation. Our artefact spotlight section covers individual pieces from recent Saqqara seasons in more detail.
Questions about Egypt's restoration programmes
It varies enormously depending on object type, scale and the resources allocated. A single painted coffin may take six months of treatment; the Tutankhamun collection project has been active for a decade and is not finished. Monumental conservation like the Sphinx is effectively a permanent maintenance programme. The timelines that appear in press releases — "restored in three years" — typically describe one phase of a much longer process.
Yes, selectively. Egypt has a substantial trained conservation workforce of its own, and the Ministry of Tourism and Antiquities sets the terms for any international involvement. Japanese specialists have worked on the Khufu boat. German, Italian and Polish teams have historical involvement at various sites. In most active projects, international partners work alongside Egyptian conservators rather than independently. The structure varies project by project.
The Grand Egyptian Museum's conservation centre is partly visible to visitors — laboratory spaces are viewable through windows, and the museum has made this a deliberate interpretive element. At the Egyptian Museum Tahrir, some treatment work is visible in the open-access galleries. On archaeological sites like Saqqara, public access during active conservation seasons is limited for practical and safety reasons. See our behind-the-scenes section for more on what access is available.
Objects in irreversible decline are prioritised for documentation — high-resolution photography, 3D scanning, pigment sampling — so the informational record survives even if the object does not. Some are placed in controlled-environment storage rather than display, where reduced light and stable humidity slow further deterioration. Deaccessioning is not practised in Egyptian state collections; the object stays in institutional care regardless of display potential.
A selection of the 2020 Late Period coffin discoveries is now in the Grand Egyptian Museum's gallery spaces. Other pieces are in the Egyptian Museum in Tahrir, and some remain in conservation storage. The distribution depends on conservation status and the receiving institution's available display space. Coverage of specific objects and where they ended up is available in our artefact spotlight pages.
