Visit of the Gediminas Tower. It is one of the main buildings of the Vilnius Castle Complex, and one of the few that survived until today. It dominates the landscape from the top of the Castle Hill, from which we will admire a splendid view of the historical centre. Constructed in 1409, this octagonal tower is 48 m high. Entirely built in red brick, it hosts a small museum presenting various documents about the glorious past of the city.
