Narva Alexander's Cathedral is the biggest church in Estonia. The project of the church was drawn by Otto Pius von Hippius and it was built between 1881 – 1884. The plot of land for the church was a gift from Georg v. Kramer, the owner of Joala mansion. The owner of the Krenholm Manufacture paid the building expenses and the church was built to accommodate 5000 workers of Krenholm Manufacture and had 2500 seats.
Church was built in Romanesque style. The height of the main building is 25,5 m and the belfry in the western part of the church was 60,75 m high. The organ with 30 stops was built in Walcker factory in Germany.
On the 6th of March 1944 the soviet army bombed Narva, damaging the roof of the church. On the 24th of July on 1944 the tower was destroyed, allegedly by the leaving German army.
The divine services were held in this church until 1962, when the soviet authorities forced the congregation to leave The church was converted into a storehouse. In 1990 the Cathdral was returned to the congregation and now the restoration works are lead by Villu Jürjo, the present minister of the church.
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.
