Coinciding with the celebration of the International Day for Monuments and Sites, we present Clifford’s Tower restoration, a Norman castle in York, a project recently completed by the English architecture studio Hugh Broughton Architects and the conservation architect Martin Ashley using intelligent and sustainable solutions made with a wooden structure that is finished with a rooftop observation deck.
The 13th Century tower and former seat of royal power in the north of England, Henry III’s stone tower is sited on William the Conqueror’s grasses motte. The daffodils, planted in remembrance of the martyred Jews of York of 1190, are in bloom, surrounding the limestone monolith known as Clifford’s Tower.
York's Clifford's Tower ruin, which sits atop an 11m mound, is one of the city's most famous landmarks, is to reopen after a €6m revamp.

New walkways, stairs and a roof deck designed by Hugh Broughton Architects will allow visitors to see previously inaccessible parts of the structure.
The geometry of the tower has the shape four-leaf clover plan, and at one time had a square tower at the centre marking the centre point of the renovation.
The result is a spartan interior with four giant columns made of sustainable glulam timber dominating the space and holding up the entirety of the new structure, including the roof canopy and steel walkways. The columns, majestic in scale, are a modern architectural insertion that feels measured and soft, indeed, like “a landscape made of wood,” as Broughton describes it.
A raft of conservation work was also carried out on the tower, including repairs to turret stairs, arrow slits, fireplaces and damaged stonework. The intervention was a delicate operation and necessarily involved consultation with the inhabitants of York throughout the design process.

Project description by Hugh Broughton Architects
Our work for English Heritage at Clifford’s Tower, in the centre of York, demonstrates our skills in designing technically challenging and appropriate interventions within the context of a Scheduled Ancient Monument, improving access and visitor facilities whilst fostering better interpretation of the site and Monument’s history.
Following a design competition, Hugh Broughton Architects, working with conservation specialists Martin Ashley Architects, were selected to repair historic fabric and create enhanced visitor facilities at Clifford’s Tower. The brief required an ‘inspiring and sensitively designed new structure within the historic monument’ with improvements to access, interpretation and facilities for visitors and staff. The project includes vital conservation works as well as architectural improvements which enhance the visitor experience.
Clifford’s Tower, standing on a tall earthen mound, is the largest surviving structure from the medieval royal castle of York. The stone tower was built in the mid-13th century but has stood as a roofless ruin since a fire in 1684. The Tower sits next to three Grade 1 listed buildings grouped around the Eye of York. One of English Heritage’s most visited buildings, the tower is an evocative survival from the medieval castle and offers superb views over the city, but previous facilities were poor, and visitors often described their experience as ‘underwhelming’.
To address the shortfalls in experience and facilities, a timber structure has been installed to partially cover the ruin and provide fantastic viewing and activity space at roof level. Suspended metal walkways give access to previously unseen features at first-floor level, enhance access to the roof and help celebrate the ruin. The structure of the intervention rests on a raft foundation, which spreads load without impact on archaeology within the tower.
The existing stairs up the motte are steep and have no intermediate landings or stopping points. To improve access, several options were explored in consultation with stakeholders, specialist consultants and members of the public, leading to the adopted strategy to improve the existing stairs by introducing additional handrails and three resting points to the sides.
An enlarged public area at the base of the motte incorporates interpretation and accommodates an English Heritage-branded Piaggio, with an interior designed by HBA, for the sale of tickets and guidebooks. It offers a ground-level place to engage with visitors, including those unable to ascend the tower.
The design was developed in consultation with multiple stakeholders both within English Heritage and Historic England and in the wider city community including the Museums Heritage Trust, York Civic Trust, City Council and the Conservation Area Advisory Panel.
