Trsat Castle is a medieval fortress located on a hilltop overlooking the Croatian city of Rijeka. The castle was originally built in the 13th century and underwent several transformations over the centuries. In the 19th century, it was abandoned and fell into disrepair, but was later restored to its current state in the 1950s.

The castle consists of several buildings arranged around a central courtyard. The main structure, known as the Frankopan Castle, was built in the 15th century and features a tower, a chapel, and a loggia. The tower provides panoramic views of Rijeka and the surrounding area.

In addition to its historical significance, Trsat Castle is also a popular cultural destination. The castle hosts numerous events throughout the year, including concerts, exhibitions, and theater performances. The courtyard is often used as a venue for outdoor events, and there is a restaurant on site that serves traditional Croatian cuisine.

Trsat Castle is easily accessible by foot from the center of Rijeka, and there is also a small parking lot nearby for those arriving by car. Visitors can explore the castle on their own or take a guided tour to learn more about its history and architecture.
