Founded 1838 when former schoolroom was converted into chapel. The present chapel was built in 1868. The attached vestry/schoolroom at right angles to rear is said to have been converted from the 1838 chapel around 1896/8, but its appearance is now all late C19.

In centre bay, large wheel-window of 10 lights; below this, paired round-headed doorways, floral capitals to jambs; boarded doors with overlights.
