Cathedral of the Holy Trinity, Gibraltar
Gibraltar, United Kingdom · built 1825
The Cathedral of the Holy Trinity is the cathedral for the Church of England Diocese of Europe. Located in Cathedral Square, it is sometimes referred to simply as Gibraltar Cathedral, although it should not be confused with the Cathedral of St. Mary the Crowned, which is Gibraltar's Roman Catholic cathedral. The cathedral is particularly notable for its Moorish revival architecture, particularly in its use of horseshoe arches. This is an architectural style inspired by Moorish architecture, appropriate given the period of Moorish control in Gibraltar's history.
