From Guildford Square (right in front of the pier), head for the castle, which you can see from the south west corner of the square. Walk past the front of the castle and then turn left to go round the western side. You’ll see the church across the road, next to the Credit Union, which is on the corner. The picture shows what you’ll see when you come round the corner. The church is in the middle, forming the ground floor of a tenement block, between the Job Centre (left, white building with green sign) and the Credit Union (right, with shop front). The church door is by the black sign with the church name on it.
