The Piotrków Trybunalski Royal Castle is a Gothic-Renaissance structure, today a museum. The stronghold on the left bank of the Strawa River existed in the 13th century. The conventions, which were held here in the 14th century gave the city greater importance in the Kingdom of Poland and according to contemporary chronicler Jan of Czarnków, Casimir III the Great ordered a residence to be built here, which was accomplished in 1347. It consist of the royal council, called the senate, and the chamber of deputies.
In the following years the building become inadequate for the purposes of the royal court. Therefore, the court architect of king Sigismund I the Old, Benedykt Sandomierski erected a new residence, which was completed in 1519. The new residence was built in the Renaissance style in the shape of a residential square tower. The structure was crowned with a profusely decorated attic. In the 16th century, the castle was the site of frequent regional councils and synods. During the Deluge the it was burned by Swedish-Brandenburgian troops. The reconstruction took place between 1668–1671 supervised by Michał Warszycki, sword-bearer of the Crown. The fortifications were not restored as well as the demolished attic, and the whole structure was crowned with a pavilion roof.
With the Second Partition of Poland the castle again fell into disrepair. in 1869 the Russian Governor of Piotrków undertook a restoration to convert the former royal residence into a garrison Orthodox church. The building suffered again during World War II. After the war the Regional Conservator recommended to rebuild the castle by the state before Warszycki's reconstruction, restoring its Renaissance features. Eventually the structure was rebuilt between 1963–1969, without restoring the Renaissance attic.References:
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
