Guildford Cathedral
A 1930s brick built cathedral which was the first to be built on a new site in the south of England since the Reformation. The inside is more impressive than the outside. The cathedral was started in the 1930s, but it wasn't until 1961 that it was consecrated due to an interruption in construction due to World War II.
The Wey Navigation
(http://www.nationaltrust....) is the canal that winds its way through Guildford until it reaches the River Thames in Weybridge. Of particular interest is the HQ at Dapdune Wharf, but just sitting down by the locks near the Yvonne Arnaud Theatre watching canal boats is very peaceful and gives one an insight into what the Wey once was - a busy industrial thoroughfare connecting Guildford and Surrey's industries with the rest of the country - and you might even get to help open the locks for the boat!
Guildford Castle and Grounds
Medieval castle built to protect the town in the 1400s and one of Henry III's most luxurious residences. Recent conservation work revealed a 12th century first floor chamber which is now open to the public.
