Tallinn has a beautiful medieval Old Town with city walls and towers. The city hall, which was first mentioned in 1322, can be seen as the centre of the city. It is enclosed by many other old buildings. The viewing platform of the city hall offers an amazing view over the city, the port and the bay. The emblem of the city, the figure of the city servant “Old Thomas” (Vana Toomas) adorns the peak of the tower.
Close by, you can find one of the oldest pharmacies in the world, the "Raeapteek,“ which was first mentioned in 1422. Also worth a visit is the Church Nikolai (Nigulsite kirik), a nice example of the old common merchant churches whose truss was usually used as a storage room, the Holy Ghost Church (Pühavaimu kirik) with an late medieval winged altar, the Olai Church (Oleviste kirik), named after the Norwegian king Olaf II, as well as the Russian orthodox Alexander-Newski Cathedral (Aleksander Nevski katedraal) with its distinctive onion towers. It was built between 1894 and 1900 as a sign of Estonia becoming Russian.
But Tallinn has even more to offer, for example the medieval castle on the same hill as the cathedral, which has only the walls in the north and west and three towers still standing. There is also the representative castle, which is today the seat of the parliament and the government.
