In 1825, an anonymous donation allows for the foundation of the Granary Chapel in the Porta del Popolo, which gained a permanent chaplain in 1828 and fell under the jurisdiction of the Diocese of Gibraltar in 1842.

Those who considered the clergy at the Granary Chapel too ritualistic separated and established a new church, Holy Trinity, which saw various iterations of building and location.

Despite delays and a lack of funds (the incumbent Canon Wasse had to cover remaining construction expenses), the church was considered completed by 1887.

During the latter half of that century, the church saw many distinguished visitors, including the Princesses Elizabeth and Margaret, and Archbishops of Canterbury Ramsey and Fisher.

[6] The church has a typical design of a central nave flanked by two aisles, gothic pointed arches and flying buttresses, surmounted by a wooden roof.

[3] Interior In the central nave, the columns and pillars are polychromed with marbles from across Southern Europe: green Carrara, red Perugia, black Verona and Yellow Siena.

[7] The pulpit is in yellow Siena and black Verona marble with white Como highlights, dedicated to the memory of Canon Wasse.
