Tallinn

From this spot, with a little stretching and bending, you can see the tops of all five of Old Town's spires. Today, the square remains the social heart of the city, a venue for open-air concerts, handicraft fairs and Medieval markets. Each winter, it's home to the town's Christmas tree — a tradition that stretches back to 1441 — and a buzzing Christmas Market. In spring it hosts the Old Town Days festival, a modern version of a medieval carnival, where traditions from the Middle Ages are kept alive.

With the help of modern multimedia, the Seaplane Harbour in the wooden architecture suburb Kalamaja tells exciting stories about the Estonian maritime and military history promising a "sea full of excitement" for the whole family in an area that would take nearly 2 million A4 paper sheets laid down side by side. The museum’s display that comprises of more than a couple of hundred large exhibits revitalizes the colourful history of Estonia. In the outdoor area, visitors can tour a collection of historic ships, including the Suur Tõll, Europe's largest steam-powered icebreaker.

A trip to Tallinn isn’t complete without a visit to this magnificent northern Baroque palace, built by Peter the Great for his wife, Catherine I, in the early 18th century. Designed by Italian architect Niccolo Michetti, the grandiose palace and surrounding manicured gardens are a humbling example of Tsarist extravagance, but just as important a reason to visit is that this is also home to the foreign art collection of the Art Museum of Estonia.
