Toompea Castle was erected on the foundations of the crumbling eastern wing of the fortress built on this site in the 13th and 14th centuries. The castle with its late Baroque façade was built between 1767 and 1773.
The history of Toompea is the story of the rulers and conquerors of Estonia, each of whom moulded and reinforced the place to their own needs and according to their own taste. Today the castle is home to the Riigikogu (the Estonian parliament). The blue, black and white of the national flag can be seen flying on top of the 45.6-metre Tall Hermann tower as the symbol of Estonia's independence.
Free excursions of the castle for single visitors, as well as groups take place every day from Monday to Friday if booked ahead of time. Sessions of parliament can be watched from the public gallery.
Tallinn has its very picturesque old town enclosed within the medieval walls with a few stunning old castles. The crumbling turrets and towers of the castles were often depicted in old Soviet films...
Toompea Castle is actually part of the parliament building so you can't miss it. It is very old and nice so go there and enjoy.
The parliament building is situated in the upper part of Tallinn opposite the cathedral. The gardens to one side are pretty and a nice place to have a rest in the shade on a warm day.
