Villa Ammende is one of the best examples of early art nouveau style in Estonia. The grand villa with a large garden was built in 1905 and belonged to the Ammende merchant family. The façades and interiors of the house were abundant, rich in detail and diverse, but also very stylish. The family went bankrupt after the First World War and the villa was sold to Pärnu City. The house has been used as a summer casino and a club. The villa has now been restored and turned into a luxurious hotel and restaurant, and it looks more stylish and art nouveau than even before. Concerts and art exhibitions are often held in the villa and guests can also enjoy its beautiful green garden.

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.
