Last monday i've received an envelope from Estonia with 10 unesco cards but I already had all the sites. However i picked these 2 beautiful cards from Estonia and Latvia.
This Tallinn card shows the St. Olaf Church and Fat Margaret's Tower.
"Once upon a time, from 1549 to 1625 to be exact, this 13th-century church was the tallest building in the world. But its gigantic, 159-metre spire, which was probably meant to act as a signpost for approaching ships, also turned out to be a very effective lightning rod. Throughout the church's history its steeple has been hit repeatedly by lightning, completely burning down the structure three times.
Nowadays its smaller, 124-metre steeple still dwarfs most of Tallinn’s buildings and remains an important symbol of the town. From April to October, visitors can make the vigorous climb to the top of the stone portion of the tower for magnificent and dizzying views of Old Town, Toompea hill and the port.
The church itself dates back to at least 1267 when it is thought to have served a group of Scandinavian merchants who settled in the area. Various legends insist the church got its name from either the giant or the mysterious stranger who built it, however it was in fact dedicated to King Olaf II of Norway.
Standing guard at the north end of Pikk street are two of Tallinn's most impressive defensive structures, the Great Coastal Gate (Suur Rannavärav) and Fat Margaret's Tower (Paks Margareeta).
The origins of Fat Margaret's name are a mystery. Some theories insist it was named for one of its larger cannons, while others hint at a cook called Margaret who once worked here.
In any case, the tower has served a number of different functions throughout its history. It has been used a storehouse for gunpowder and weapons, and as a prison.
Now it's home to the Estonian Maritime Museum, which provides a detailed look at the nation's seafaring past. Visitors should be sure to climb up to its rooftop viewing platform to get a lovely view of Old Town and the bay." - in: http://www.tourism.tallinn.ee/fpage/explore/attractions/old_town#!p_174824
