The chapel of Templars - Rosslyn (Edinburgh) - Scotland. Roslyn Chapel was one of my favorite places. Founded in the century by William Sinclair who was descended from a noble family of Norman knights. It is said to have many Knights Templar symbols.
St. MacDara's Church, St. MacDara's Island, off the coast of County Galway, Ireland. Internally, the church measures only 15 feet by 11. Carna is in Connemara in the west of Ireland. Connemara is a beautiful, remote area, not good for farming, so it never boasted much of a population, and due to its remoteness, the English never quite managed to take it over.
