St. Bartholomews Church was built in 1972, a very modern and striking looking church both inside and out.
You are looking for a magnetic nano, you do not need to enter the church grounds to retreive it, you are best off parking in Colchester Road as the cache is at the rear gates. You would be wise to bring your tweezers.
