The present Dromore Cathedral was originally constructed in 1661 by Jeremy Taylor, Bishop of Down and Connor and has been several times expanded to its present size.
The first church on the site was a wattle and daub building constructed by St Colman circa 510. This was replaced by a medieval church which was destroyed in the late 16th century. The church was again rebuilt and in 1609 elevated to the 'Cathedral Church of Christ the Redeemer' by Letters Patent of James I. In 1641 this building, too, was destroyed.
The present building was first constructed under Bishop Jeremy Taylor in 1661 as a narrow church 100 feet (30 metres) long. In 1811 Thomas Percy (bishop of Dromore) added a short aisle at right angles to the nave to form an L-shaped floor plan. In 1870 a semicircular sanctuary and organ aisle were added. Finally in 1899 an additional aisle parallel to the original nave aisle was added to achieve a conventional rectangular floor plan.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
