St Bridget's Cathedral in Kildare is a 13th century building rebuilt in the 19th century. It consists of a single-nave body with a transept and a rectangular closed chancel. There is a square tower above the intersection of the naves.
The place where the cathedral stands is connected with the life and activity of the fifth-century Irish saint, Bridget. She was supposed to build a small wooden church here. Later there was an early Christian oratory here, and the present cathedral was built around 1220. Over the centuries, it was damaged many times, so that in the 19th century it had to be completely renovated. It used the 13th century walls, but the whole building received a lot of neo-gothic elements.
The cathedral is built on a cross plan. The chancel is closed with a tall, split window decorated with a stained glass window. The stained glass windows also decorate the nave windows. The interior is covered with a gable roof, the structure of which is visible from the nave side. The interior design comes from the 19th century.
