The foundation stone of the Ealing Welsh Presbyterian Chapel, Capel Seion, was laid by Margaret Lloyd George in 1908, and the church building was completed in 1909.
The building is set back from the road, behind the Welsh cottage, and is not generally open to the public. It holds services in Welsh every Sunday. Next door is the church hall, which is used for concerts, meetings and nurseries.
You do not need to visit the church location unless you want to. The cache is located a short walk away. To find it, solve the puzzle. All the information you need is on this listing (although you may need to view the page on a computer rather than a phone).
