Although the foundation stone on this monumental cathedral, also known as St. Anne’s, was laid in 1899, it remained incomplete for more than a century; even now it still awaits a steeple. Blending architectural genres from Romanesque to Victorian to modern, the huge structure is more attractive inside than out. In the nave, the ceiling soars above black-and-white marble walls and stone floors, and elaborate stained-glass windows flood it with color on a sunny day. Carvings that represent life in Belfast top the 10 pillars. The cathedral’s most impressive features are the delicate mosaic ceilings of the tympanum, and a baptistery constructed of thousands of pieces of glass.
