The Book of Llandaff refers to the existence of a church, or monastery, on this site in about 735. The existing St. Peter's Church, now substantially rendered and whitewashed, consists of a nave with a separate chancel, a vestry, a tower to the west, and north and south porches. The oldest parts of the building, including the herring-bone masonry in the north wall of the nave, may have an Anglo Saxon origin or, alternatively, date from the 12th century. The nave seems to have been lengthened during the 13th century, perhaps when the tower and chancel were built. A small window in the southwest corner dates from the early 14th century. The exposed Old Red Sandstone walling in the chancel dates from the 14th century; the chancel has a sanctuary window on each side, a priest's door, and an ancient stone bench outside. A royal coat of arms dated 1711 is painted on a board inside the church.
The north porch and vestry were added in 1824, and the whole church was restored in 1861–62. Inside the church are five stained glass windows.
The church is too low-lying to prevent winter floods from entering the building, and brass plates near the chancel arch record the heights of notable floods. A new balcony has been constructed at the back of the church so that perishable items can be kept above the floodline. This balcony is decorated with a beautiful oak screen. The church had a rectory, which was later known as Dixton Cottage.
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.
