Rosslyn Chapel was founded on a small hill above Roslin Glen in the mid-15th century. The chapel was founded by William Sinclair, 1st Earl of Caithness of the Scoto-Norman Sinclair family.
After the Scottish Reformation (1560), Roman Catholic worship in the chapel was brought to an end, although the Sinclair family continued to be Roman Catholics until the early 18th century. From that time the chapel was closed to public worship until 1861, when it was opened again as a place of worship according to the rites of the Scottish Episcopal Church, a member church of the Anglican Communion.
Since the late 1980s, the chapel has also featured in speculative theories concerning a connection of Freemasonry, the Knights Templar and the Holy Grail. It was prominently featured in the 2003 bestselling novel The Da Vinci Code and its 2006 film adaptation. Numerous books were published after 2003 to cater to the popular interest in supposed connections generated by Brown's novel. The chapel, built 150 years after the dissolution of the Knights Templar, supposedly has many Templar symbols.
Rosslyn Chapel remains privately owned. The current owner is Peter St Clair-Erskine, 7th Earl of Rosslyn.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.
