Alexander Nevsky Cathedral

Highlight ‱ Religious Site

The large and richly decorated in historical mixture style Christian Orthodox Church was completed in 1900 on the Toompea Hill, at the time Estonia was part of the Tsar Empire. The well-preserved cathedral is Tallinn's most generous example of Christian Orthodox sacred architecture. In the towers of the church is Tallinn's most powerful church bells ensemble. It consists of 11 bells, including Tallinn's largest 15-tonne bell. The whole carillon of the ensemble can be heard before the services. The decorated with mosaics and icons interior is worth the visit.

Town Hall Square, Tallinn

Highlight ‱ Historical Site

As a central square in the Old Town, the Rathausplatz still plays an important role - in summer the square fills with outdoor cafés, the old town days and the medieval days are celebrated, open-air concerts, markets, etc. take place. In the winter, the Rathausplatz turns into a magical Christmas market, in the middle of which sits a proud Christmas tree. The tradition of the Christmas festivities goes back to the year 1441, when the brotherhood of the Blackheads erected a Christmas tree there for the first time.

Toompea Castle was built on the sunken foundations of the east wing of the Toompea Fortress built from the 13th to the 14th century. The castle with its late Baroque facade was built 1767-1773.
The story of Toompea is the history of Estonia's rulers and their power. Each ruler has built and secured this place according to his needs and wishes. Today, the Parliament of the Republic of Estonia works here, and the Estonian blue-black-and-white flag - the symbol of the independent state of Estonia - blows on the 45.6-meter-high tower of the Long Hermann.
