Our normal working hours from Monday to Saturday are from 9 o抍lock in the morning to 6 o抍lock in the evening. On Sunday we open at the later time of 10.30 and close at the earlier time of 3.30. From our office you can get information about hotels, restaurants and cinemas in the city. Why not take a bus tour? There are bus tours of the city every day which start at 11 o抍lock. They start from Castle Square. Tours take about 2 hours and go around the historic city centre and along a part of the river. The cost of a ticket is 3 pounds.
