St Peter's Church in Riga is known for its tall tower, which offers stunning views of the city, including the red roofs of Old Town, the modern part of Riga, Riga Bay, and the Daugava River with its large port. The church itself was originally built in 1209, but only a few walls and pillars remain from that time. The Gothic tower, which was over 130 meters tall, was completed in the late 15th century. However, it collapsed in 1666 and was rebuilt in the Baroque style in 1690–at the time, it was the tallest wooden structure in the world. In 1721, the tower was struck by lightning and burned down. It was later restored, but once again it burned down during World War II. Renovation of the tower began in 1967, and today, it stands at a height of 123.25 meters. Visitors can access the second gallery, which is 72 meters above the ground. In 1997, St Peter's Church was added to UNESCO's World Heritage list.

This series of broad white steps descending into the sea are one of the most unique landmarks in Zadar. Designed by the local architect Nikola Bašić, the Sea Organ consists of underwater resonant chambers carved in the steps which allow the organ to play chiming notes when the water flows into them.
