Mästerby Church dates largely from the 13th century. The nave, choir and apse were built first, at the beginning of the century. In the middle of the same century, the tower was also built. The nave was made higher about a century later, and at this time both the nave and choir received vaulted ceilings. The church has remained relatively unaltered since the end of the Middle Ages. Only the sacristy is significantly later, added in 1790. New windows were also made in the 1860s.
The church is richly decorated with frescos internally. They range in period from the 13th to the 17th century. In the apse, some Romanesque paintings survive, notably a depicting of Mary, while some have been covered with other paintings in the 17th century. The vaults in the nave are decorated with frescos from the 14th century, and the walls of the nave furthermore decorated by the artist sometimes referred to as the Master of the Passion of Christ (15th century). Still other frescos, in the choir, probably date from the 16th century, while another set, again in the nave, is dated to 1633.
The baptismal font is from the 12th century, Romanesque in style and a work by the sculptor known by the assigned name Byzantios. The triumphal cross is locally made, dating from the 13th century. Other furnishings date from the time after the Reformation.References:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
