A lovely spot in Krk is the harbor, with its many pubs and restaurants:
And what about Frankopan Castle? According to Wikipedia,
Frankopan Castle on Kamplin was raised by Croatiannoble family of Frankopanthrough several centuries and several generations. After the death of the first Duke Dujam, his sons continue to dominate over the island and the town of Krk. (…) The round tower on the northern corner of the castle with a transversely extended lower part, was built after the square, probably in the 13th century. It was restored around 1480, and again around 1600. On the tower there is bricked inscriptionAureae Venetorum libertati with lions of St. Mark, which dates from 1500. This cylindrical tower has two floors and attic. On the ground floor once there were two doors, one open to the Kamplin, and the other toward the interior of the castle. On the eastern part of the castle, overlooking the sea there is still a square tower, while on the western part of the castle there was a sentry box for guard. Within the complex there was space for soldiers. It is not known precisely when, but the entire complex was completed before 1348.
