Monkton Old Hall is a Grade I listed building in Pembroke. While the chimney is of Norman architecture, the rest of the building dates from the 14th century and it underwent restorations in the late 19th and early 20th centuries.
The building was originally a guesthouse for Monkton Priory, located nearby. The current building mostly dates from the 14th century, but the chimney is of earlier construction in the Norman architectural style. After the dissolution of the Monasteries, the building was split up into multiple tenements. J.R. Cobb began a restoration in 1879, as it had been reduced to a ruin consisting of an empty shell. These renovations included the addition of the present roof.
Further modifications took place post-1933, with the addition of leaded windows.
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.
