Built between 1842 and 1870 on the former site of a Franciscan convent, The Stock Exchange Palace, or Palácio da Bolsa, is an impressive building in Neoclassical style, which currently houses the headquarters of the Porto Commercial Association. Classified as a World Heritage Site by UNESCO, the Palácio da Bolsa attracts around 200,000 visitors a year, making it the most visited monument in the north of Portugal. Take a guided tour to see up close its magnificently decorated rooms, especially the Arab Room, which features the exotic Moorish Revival architecture. This room also serves as a reception hall for heads of state and personalities visiting the city.

The Al-Qurain Martyrs Museum is a profoundly moving and sobering historical site, preserving the original house that was the scene of a brutal, day-long battle during the 1991 Iraqi occupation. The building itself is the primary exhibit, left in a semi-destroyed state with visible bullet holes and structural damage. It commemorates the resistance fighters of the Al-Messilah Group who chose to fight rather than surrender. A guided tour is highly recommended to fully understand the narratives of sacrifice and resilience, making it an essential visit for those seeking to comprehend a pivotal moment in modern Kuwaiti history.

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.
