The Bells Monument outside the city centre of Sofia was installed in 1979, when UNESCO declared it International Year of the Child. The monument presents more than 70 bells from across the world, on pillars that are marked with a message from children from the respective nation. Occasionally, the seven main bells, one for each continent at the top of the central pillar, ring along to parades or events held around the monument.

The Långe Jan lighthouse — 'Tall John' — first cast its light over the Baltic waves on November 1, 1785. Rising from the craftsmanship of, perhaps, Russian prisoners of war, it stands as a beacon of history and maritime safety on Öland's southernmost point. Initially measuring a soaring 36 meters and requiring a 197-step ascent, it now proudly stretches to 41.6 meters, claiming the title of Sweden's loftiest lighthouse. Once cradling an open flame against the Nordic sky, Långe Jan has seen transformations from bare stone, borrowed from a bygone chapel, to a whitewashed pillar with a distinguishing black band. Surrounded by the thriving Ottenby bird station, Långe Jan's legacy is as enduring as the coastal winds, welcoming visitors each summer to scale its heights and embrace a panoramic sweep of sea and sky.

This is the most popular tourist attraction in Sofia. The beautiful orthodox cathedral was built in 1912 and took 30 years to complete. The cathedral was created in honor of the Russians soldiers that died in the Russo-Turkish war and holds up to 10,000 people.
