St Collen's Church is a parish church in the town of Llangollen, Denbighshire, Wales. The first church on the site was founded by Collen in the 6th century. Nothing of this building remains. A new church was built in the 13th century, in the Early English Gothic style. This was developed in the succeeding centuries, and then almost completely rebuilt in the 19th century. The architect of the Victorian reconstruction was Samuel Pountney Smith, who retained little of the earlier church, with the exception of the tower. The churchyard contains the grave of the Ladies of Llangollen, Eleanor Charlotte Butler and Sarah Ponsonby, and their servant Mary Carryl, who lived at the nearby Plas Newydd.
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.
