Heritage Open Day: St Leonards-on-Sea Congregational Church is a striking Grade II listed Victorian Gothic building dating from 1864. Built during the town’s rapid expansion, it served the local community for nearly 140 years before being carefully restored & reopened. St Leonards-on-Sea Congregational Church, prominently situated at the junction of London Road and Pevensey Road, is one of the finest Victorian Nonconformist buildings in Sussex. Founded in 1863 by local philanthropist James Griffin and designed in the Gothic Revival style by Edward Habershon, the church opened in 1864 and quickly became a landmark in the growing seaside town.
