The building erected in 1875 replaced an earlier chapel on the corner of Llewelyn Avenue and Vardre Lane. The first Tabernacle chapel in Llandudno, dating from 1815 was itself rebuilt in 1835. The chapel was extended in 1902 by G.A.Humphries to incorporate the schoolroom, the ionic-pillared portico and a new main entrance.
The chapel closed in 2013. The adjoining schoolroom is used as an exhibition centre.
A plaque records that the chapel's minister, the Rev Lewis Valentine was one of the three Welsh nationalist activists who made an arson attack on the RAF Bombing School at Penyberth, Pwllheli on 8 September 1936.
The red plaque reads:
