St. Garmon's Mound, or `Twmpath Garmon? is in the churchyard of St. Garmon's Church (NPRN 146204). The broad raised mount of earth on the north side of the church is traditionally held to be the preaching mound of the ninth century Celtic saint. There are a number of graves within the mound and it is now considerably overgrown.
