The older lighthouse of Suurupi was built in 1760. The round old-style stone tower was built near the end of the reign of Czarina Elizaveta Petrovna, this is a magnificent example of classic Russian Imperial lighthouse design. The lighthouse was substantially rebuilt in 1812 and further renovated in 1858. The round watch room was added in 1951, and the present lantern was new in 1998.
The newer wooden lighthouse date back to the year 1859. It is 15 m high, square pyramidal, 4-story wood keeper's house with A-frame roof and painted in white. The light was formerly shown through a window on the top floor at one end of the building; it has been moved outside to the windowsill. A miraculous survivor of two world wars and over 150 winters, this remarkable lighthouse is a well-known historic landmark on Estonia's coastline. The top floor with its lantern chamber was added in 1885, increasing the tower height by 3.5 m.

The Erfurt Synagogue was built c. 1094. It is thought to be the oldest synagogue building still standing in Europe. Thanks to the extensive preservation of the original structure, it has a special place in the history of art and architecture and is among the most impressive and highly rated architectural monuments in Erfurt and Thuringia. The synagogue was constructed during the Middle Ages on the via regia, one of the major European trade routes, at the heart of the historical old quarter very close to the Merchants Bridge and the town hall. Many parts of the structure still remain today, including all four thick outer walls, the Romanesque gemel window, the Gothic rose window and the entrance to the synagogue room.
After extensive restoration, the building was reopened in 2009. On display in the exhibition rooms is an collection of medieval treasures discovered during archaeological excavations. This includes 3,140 silver coins, 14 silver ingots, approx. 6,000 works of goldsmithery from the 13th and 14th centuries and an intricately worked wedding ring of the period, of which only two others are known to exist anywhere in the world. A mikveh (Jewish bath) has been excavated close by (13th/14th century). The Old Synagogue, the Small Synagogue and two Jewish cemeteries together form a network of historical buildings and sites which vividly portray the role of Jewish life in the history of Erfurt.
