In the late 19th and early 20th centuries Bow saw three churches which still exist today. The Church of England St Boniface is approximately one mile out of the village at Nymet Tracey, the Top Chapel or Gospel Hall of the Plymouth Brethren is on the main A3072 road as you go out towards Crediton.
The Congregational Church, built in 1899, is where you are looking for this cache. It is located outside of the church gates. The morning service on a Sunday is held here at 11am, and you are very welcome to join the congregation, and enjoy some refreshments afterwards.
Thanks to the church for consent to site this cache. You are looking for a small container to the right of the main gate. It does not involve going into the church.
