The oldest part of the Ardre Church is the tower, dating from about 1200. The tower originally belonged to an earlier church building from the 12th century, the nave and choir of which was replaced with the current building circa 1250. The sculptured choir portal originally also belonged to the earlier church.
The interior of the church was heavily remodelled after plans by artist Axel Herman Hägg in 1900-1902, in a neo-Gothic style. The dominating wall paintings are consequently designed by Hägg. A few stained glass windows remain but were complemented by modern replicas during the renovation.
The furnishings of the church are still largely medieval: an altarpiece from the early 14th century, a triumphal cross and baptismal font, both from the middle of the 13th century, and a carved wooden Madonna from circa 1500 are all in their original milieu. The organ is an elaborate Gothic Revival piece, made for the renovation in 1902 and inspired by medieval French organs.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.
