Today Orphir contains the remains of Scotland's only surviving circular medieval church. Built in the late 11th, or early 12th century, the Orphir Round Church is thought to have been built by Earl Hakon. Dedicated to Saint Nicholas, its design was inspired by the Church of the Holy Sepulcher in Jerusalem.
At the time of the church construction, the Great Crusades were in full swing and the circular church had become a popular design with returning crusaders attempting to copy the famous structure in the Holy Land.
Originally, the church consisted of a circular nave just over six metres in diameter and an apse. The apse remains today, along with a small section of the nave's eastern section.
The church survived, almost complete, until the middle of the 18th century when sections were pulled down and the stone used to construct the new parish church. The replacement parish church did not last and no trace survives today.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
