This octagonal Georgian brick structure (entrance on Mark’s Lane) serves the United Church of Jamaica and Grand Cayman. It was built from 1813 to 1819 by a group of prominent Scottish merchants and is surrounded by a gallery supported by Corinthian pillars. Note the white-on-blue St Andrew’s cross in the stained-glass window. You’ll be amply rewarded if you visit during a service, when its acclaimed choir, the St Andrew Singers, performs.
