The Queen is set to officially open an ancient castle and jailhouse which has been transformed into a luxury hotel, restaurants and an art gallery.
The castle, formerly used as a prison, has been turned into a hotel
The final part of the redevelopment of the 11th Century Oxford Castle will be completed in May.
A formal opening ceremony will be headed by the Queen when she visits the city on 5 May.
The site includes St George's Tower and the Castle Mound, which are some of the oldest structures in the city.
The Malmaison chain has spent £20m on turning the prison at the centre of the site into a hotel.
The jail building is attached by a tunnel to the former county Assize Court.
It has not been used as a prison since the 1990s and more recently it has been used as a film set on several occasions, with stars such as Gerard Depardieu, Glenn Close and Brad Pitt filming there.
