Tallinn is the capital of and the largest city in Estonia. You can witness the influence of the 14th and 15th century architecture in the city, as it was able to preserve its heritage. The ancient times seem to live in the old town of Tallinn where you can see a mix of centuries old walls, towers, and pavements. However, the rest of the capital bears the modern touch. There are a number of attractions that are enticing—the Estonian Art Museum, Kiek-in-de-Kök (a tall and solid tower built in 1475), 19th-century Russian Orthodox Alexander Nevsky Cathedral, and Lutheran cathedral Toomkirik.
Tartu, on the other hand, is the intellectual capital of Estonia, as opposed to Tallinn being the political and medieval capital. The city, which is also branded as the University Town, has a laid back clime with approachable and modest people.
Pärnu has to be the summer capital of Estonia and is a popular getaway for people who want relaxation. It lures tourists with its unadulterated shores and a good range of festive events. The environment is serene and very suitable for people who want to escape the stress of the urban world. One can enjoy the serenity or the mud baths.
