The 17th century St Paul's Cathedral on Ludgate Hill is one of the capital's most iconic buildings. Designed by the illustrious Sir Christopher Wren, St Paul's was the tallest building in London until as late as 1962. Use the touchscreen multimedia guides or take a guided tour to learn about the famous interior or, if you're feeling fit, climb up to the Whispering Gallery and try out the acoustics. From there you can carry on making your way up to the Golden Gallery atop the dome, where you'll be rewarded with breathtaking views of London. You can also descend into the crypt where you'll find memorials of important historical figures such as Admiral Lord Nelson.

Kaunas was a significant cultural base of the Jews living in Lithuania; its Jewish community amounted to one third of the city's inhabitants, and the ghetto set up here further increased their number. Fort IX is a stronghold and museum that commemorates Kaunas's eventful history, and the people who were killed or imprisoned here under the WWII Holocaust.

Embarking on a funicular journey is a unique experience in Kaunas, as this is the only city in the Baltic states where this means of transport is available. The Žaliakalnis, built in 1931, is one of the oldest funiculars still in operation in the world. The other funicular in Kaunas, Aleksotas is much sought for the view you'll get (of the Old Town) once you reach the hill of the same name.
