Originally known as Sancti Petri de Portu, many regard the Town Church as the Cathedral Church and the finest in the Channel Islands. The first mention of the church in official documents was in 1048 when it is thought to have been given to the Abbot of Marmoutier by William of Normandy. It is likely that the original building was made of wood. The current building was built over a 200 year period with the chancel completed in the 12th century and the chapel added in 1462. The church was completed in 1475. However restoration work was carried out to the spire in 1721. The bells were recast in 1736 and in 1913. The clock was installed in 1781. Up until 1886, the rows of pews went in various directions and at that time some re-alignment was undertaken.
A copy of the text of an order from Pope Sixtus IV granting neutrality to the island is displayed in the church. In 1414, the English Crown took over the church but interestingly the church paid tithes to the Bishop of Coutanches until 1548. Up until the middle 1700's, the Church was completely surrounded by street markets and houses. A stream ran past the Church and around the harbour near to Woolworths. A memorial to the famous islander Major General Sir Isaac Brock can be found inside the Church together with many other memorials.
In 2001, work started on repairing the 500 year old oak vaulted rafters in the roof, which are now rare in England and believed to be the last surviving of this type in the Channel Islands. The joints are now quite weak and are being strengthened with stainless steel plates on the ridges, but the beams themselves remain in good condition. They work the subject of public outcry when the church decided to replace the rafters in 2000, but the Ecclesiastical Court decided after taking expert advice, that the roof could be saved.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.
