Social info

Friday evening - 31st July

Early arrivers may wish to convene at The Kings Head on Quarry Street next to Guildford Castle.

The Kings Head itself is a timber-framed building dating back to the late 16th or early 17th century. It originally consisted of two separate houses, later combined to create the public house we know today. In the cellar, you can still find the foundations of a square corner of the castle’s former outer wall, which once extended down Castle Street and along Quarry Street. Renowned as Guildford’s most haunted pub, The Kings Head has been the subject of numerous paranormal investigations and is a highlight on the popular Ghost Tour of Guildford.

Join us here from 7pm onwards for a chance to socialise and yes – there will be mahjong sets available for those who wish to ‘limber up’!

You will be also able to register there for the tournament if you wish.

Saturday evening - 1st August

We invite you all to join us at The Britannia on Saturday Night which is a short walk from the playing venue and an ideal location for relaxing after the first day's play'.
