The most convenient car park is the pay-and-display off Golden Dog Lane, although there are a couple of cheaper alternatives: the Hollywood Cinema pay-and-display and the Anglia Square multi-storey car park. They are just a short walk down Magdalen Street to Golden Dog Lane.
If you are coming from outside of the City, find the inner ring road and the Barrack Street roundabout. Take St Crispins Road and make a left onto Calvert Street. Then, left again into Golden Dog Lane. The car park is on the right. There is an entrance to the Old Meeting House directly off the car park.
If you are coming from the City Centre, take St. Georges Street off Colegate and follow the road round into Cross Lane. Cross Calvert Street into Golden Dog Lane. The car park is on the right. There is an entrance to the Old Meeting House directly off the car park.
Here is a map of all the parking areas convenient to the OMH.
