The Church of Notre Dame in Brennilis was developed from 1485 through to the 16C, and has recently been restored, again.

And outside, on the Calvary, this interesting figure of Christ (1625) by Roland Doré.
Just outside the town is Ty ar Boudiged, or the Tomb of the Dwarves (!) – a covered tomb dating to c.3,000 BC. Apparently this area has been inhabited for thousands of years and there are several standing stones, dolmens, and even the remains of alignments. (Visit The Megalithic Portal for sites and information.)
A good walk, Churches, and a prehistoric tomb – a fascinating day in Brittany!
