The beautiful Saue Manor complex is one of the best examples of Estonian early classicistic architecture. The first known owner of Saue Manor was Remmert von Scharenberg from Westfaal, who received right of investiture from queen Margaret of Denmark. Before moving to Saue the would-be manor owner was the bailiff of Narva in 1528 - 1532, and hold a position in Tallinn commandery in the years 1534 - 1549. Apart from his property in the country, he also owned several houses in the town of Tallinn. He was buried in St. Nicholas' (Niguliste) Church in 1549.
The manor was acquired by Friedrich von Fersen in 1774. The present manor house together with the barn and the coach house arched round its front square were finished in 1792. Because of a mortgage deed in 1792 von Fersen was forced to relinquish the possession of the manor to the owner of Saku Manor, prince Friedrich von Rehnbinder and his wife princess Gertrud. The new owners moved in and in 1794 their second son was born in Saue, as well their next children. Even when the children had a new St. Petersburg style main building constructed in Saku, the old couple preferred to stay in Saue.
After the Independence War in 1918 when the Straelborns left for Germany and sold the manor to the Republic of Estonia. The republic gave it together with 50 hectares of land to a hero of the Independence war, Johannes Erm. Regrettably, his life was a short one and from 1925 the manor was left to his wife and family.
During the Russian occupation the manor changed occupants several times. It functioned as a home for aged people, a hospital for the chronically diseased, a machine and tractor station, the office of Estonian Agricultural Machinery, a kindergarten, the Saue city council and the office and production rooms of a firm SAUREM, belonging to the Saue city council. In 1995 the manor was returned to a daughter of Johannes Erm, Missis Elga Viilup, who in turn sold it to the Kriisa family.

The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
