Originally built between 1168-1178 by Henry II, The Castle Keep of Newcastle upon Tyne is one of the finest examples of the country's Norman Keep. Originally it contained an early mote and bailey castle built by the son of William the Conqueror, Robert Curthose. The Castle Keep is a Grade I listed building and heritage visitor attraction. It is open to the public 361 days a year and only costs a few quid to enter. Inside, there is a small museum which houses interesting exhibitions on the history of the Castle and the climb up the winding stairs is well worth it. At the top of the Castle Keep, you will be treated to wonderful views of the city, including the River Tyne, bridges and cathedral. Local theatre companies have been known to host performances in the Keep and it makes an exciting venue.
