Shortly after the assassination of singer John Lennon in 1980, this stone wall, located across from the French embassy, was converted into an impromptu memorial with a painting of the singer's face, candles, and song lyrics from The Beatles. Soon, political graffiti criticising the totalitarian regime began to appear. Despite the authorities' countless attempts to whitewash the wall, they never truly managed to keep it clean for long. Today, the Lennon Wall is an endless tribute to the freedom movement. It has lots of graffiti, drawings, and messages, and anyone who comes here is free to leave their contribution. This is also a great spot for photos.

The iconic Karlův most was built in 1357 under the guidance of Charles IV, and up to the 19th century it remained the only bridge connecting both sides of Prague. Take a stroll over the bridge and learn the names of the 30 saints whose statues stand sentinel there. Take some time to visit the Charles Bridge Museum close to the bridge itself. It is located in the several rooms of the original Crusaders hospital and Church of the Holy Spirit.

Located on the hills of Varna, the Monument of Bulgarian-Soviet Friendship is a striking example of communist-era architecture. Built to honour the Soviet Army on Turna Hill, the monument now serves as both a historical landmark and a scenic viewpoint. You can climb its 305 steps for one of the best panoramic views of Varna or even use the climb as a workout, just as many locals do.
