The Calvinistic Marthodist cause in Rhoscolyn first met in Ty'n Rhos and then in an early nineteenth century small cottage/ farmhouse, later to be known as Ty Capel. The present chapel was built in 1906 and Ty Capel converted into a stable and vestry with a schoolrooms over. The chapel is built in the Classical style of the gable-entry type and is now Grade 2 listed for its bold design and ambitious scale for a small rural community.
