In the United States, the first "Gothic stile" church (as opposed to churches with Gothic elements) was Trinity Church on the Green, New Haven, Connecticut. It was designed by Ithiel Town between 1812 and 1814, while he was building his Federalist-style Center Church, New Haven next to this radical new "Gothic-style" church. Its cornerstone was laid in 1814, and it was consecrated in 1816. It predates St Luke's Church, Chelsea, often said to be the first Gothic-revival church in London. Though built of trap rock stone with arched windows and doors, parts of its tower and its battlements were wood. Gothic buildings were subsequently erected by Episcopal congregations in Connecticut at St John's in Salisbury (1823), St John's in Kent (1823–26) and St Andrew's in Marble Dale (1821–1823). These were followed by Town's design for Christ Church Cathedral (Hartford, Connecticut) (1827), which incorporated Gothic elements such as buttresses into fabric of the church. St. Paul's Episcopal Church in Troy, New York, was constructed in 1827–1828 as an exact copy of Town's design for Trinity Church, New Haven, but using local stone; due to changes in the original, St. Paul's is closer to Town's original design than Trinity itself. In the 1830s, architects began to copy specific English Gothic and Gothic Revival Churches, and these "'mature Gothic Revival' buildings made the domestic Gothic style architecture which preceded it seem primitive and old-fashioned".
