Lincoln Castle was built in 1068 only two years after the battle of hastings and according to the Domesday Book, 166 Saxon homes were cleared to make room for the castle. The Observatory Tower shown here is built on a Motte and the Keep, or Lucy Tower, is also built on a Motte.

The castle is unusual in that it has two mottes and it is only one of two such castles in the country, the other castle being at Lewes in Sussex.

The view from the top of the Observatory Tower in the Castle, which is not the place for those without a head for heights, showing the Cathedral, the Market Place and the Tourist Information Centre - the black and white timber-framed 16th-century merchant's house on the left of the Market Place.

A view of the Inner Bailey from the castle wall near the East gate showing the Georgian/Victorian prison (red brick building) and the Crown Court beyond.

A view of the west wall with a row of terraced houses outside the wall.

You can see a glimpse of the view beyond giving an idea of the height of this hill.
