English: Lincoln Castle, Lincoln A cast metal diorama of the Castle stands between the Victorian and Georgian prisons. This is roughly the view you would get if you were flying over the castle from a southerly direction. Clockwise, starting from the Lucy Tower, which breaks up the south wall, is the Medieval 15-sided Keep standing on the original motte of the Castle. Where the south and west walls meet at the corner, is the furthest extent of the Wall Walk, the southern wall being insurmountable. Almost at the corner of the west and north wall is the West Gate. In medieval times it led to open countryside. It was sealed up in the fifteenth century and reopened again in recent times. The large building which stands near the West Gate is the working Crown Court, built between 1822 and 1826. Continuing clockwise brings us to the Bath House, which stands almost at the centre of the north wall. It was used as the prison laundry by the inmates in the 19th-century. Far right is the Cobb Hall, a 13th-century Medieval Tower, which was used for defence, imprisonment and public execution. Heading south on the east wall is the East Gate, the main exit/entrance to and from the City. The two large buildings are former prisons. Nearest the gate is the Georgian Prison building, which was built in 1787. Next to it is the Victorian Prison built between 1845 and 1846. In the south east corner of the wall and at the beginning of the Wall Walk is the Observatory Tower. The part Norman, part 14th-century square tower was built on the smaller second motte. The observatory turret was added by a governor of the prison, in the 19th-century. This tower has the highest vantage point of the Castle and provides excellent views, especially of the Cathedral.
