The Calvinistic Methodists originally met at "Tan y Graig" on "Lôn Fach" but moved to "Tal Sarnau", a house on the site of the "Memorial Hall". From here they moved again, to a site on "Stryd Fawr", rapidly outgrowing the small chapel. The neo-classical "Capel Mawr" was built on the same site in 1813. A second chapel, "Capel y Traeth" on "Penpaled Road", with a notable porticoed facade, was built at a cost of £2,040 in 1895 by Owen Roberts of Porthmadog. Previously known as "Capel Seion", it was renamed in 1995 when the congregation merged with that of "Capel Mawr", reuniting the two congregations that had separated in 1889.
