St Anne's Cathedral is unusual in serving two separate dioceses (Connor and Down and Dromore). The foundation stone being laid in 1899 by the Countess of Shaftesbury. The old parish church of St Anne by Francis Hiorne of 1776 had continued in use, up until 31 December 1903, while the new cathedral was constructed around it; the old church was then demolished. The Good Samaritan window, to be seen in the sanctuary, is the only feature of the old church to be retained in the cathedral. Initially, only the nave of the cathedral was built, and this was consecrated in 1904.
In 1924 it was decided to build the west front of the cathedral as a memorial to the Ulstermen and women who had served and died in the Great War. The foundation stone for this was laid in 1925 and the completed facade, to an amended design by the architect Sir Charles Archibald Nicholson, was dedicated in June 1927.
In the meantime, the central crossing, in which the choir sits, was built between 1922 and 1924. The Baptistery, to plans drawn up by the late W H Lynn, who had assisted Sir Thomas Drew, was dedicated in 1928, and the Chapel of the Holy Spirit, with its beautiful mosaics depicting Saint Patrick, was dedicated in 1932, the 1500th anniversary of the arrival of St Patrick in Ireland.
In 1941 the cathedral was almost destroyed by a German bomb, which caused extensive damage to surrounding properties. In 1955 work began on the construction of the ambulatory, at the east end of the cathedral. This work was dedicated in 1959, but it was not for another ten years that it was possible to begin work on the north and south transepts. The Troubles and inflation led to long delays and major problems with the financing of this work.
The south transept, containing the Chapel of Unity, and with the organ loft above, was dedicated in 1974, and the north transept, with the large Celtic cross designed by John MacGeagh on the exterior, and housing the Chapel of the Royal Irish Rifles, was completed in 1981.
In April 2007 a 40-metre stainless steel spire was installed on top of the cathedral. Named the 'Spire of Hope', the structure is illuminated at night and is part of a wider redevelopment planned for the Cathedral Quarter. The base section of the spire protrudes through a glass platform in the cathedral's roof directly above the choir stalls, allowing visitors to view it from the nave.
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.
