Trinity Congregational Church, later known as Union Chapel, is a former place of worship for Congregationalists and Independent Christians in Arundel, an ancient town in the Arun district of West Sussex, England. Protestant Nonconformism has always been strong in the town, and the chapel`s founding congregation emerged in the 1780s. After worshipping elsewhere in the town, they founded the present building in the 1830s and remained for many years. Former pastors included the poet George MacDonald. Robert Abraham`s distinctive neo-Norman/Romanesque Revival building was converted into a market in the 1980s and has been renamed Nineveh House. English Heritage has listed the building at Grade II for its architectural and historical importance.
