During the renovation of a waterfront house in the city of Krk in 1990, a Latin inscription was discovered. It records the names of two city magistrates, Turus Patalius and Venetus Lastimeis, and mentions the restoration of the Temple of Venus funded with public money. This inscription is linked to the Roman civil wars, specifically the conflict between Pompey’s and Caesar’s forces in 49 bc. The inscription can be viewed at the Fortis Gallery on Dr Dinko Vitezić Street. It is believed that Pompey’s troops deliberately destroyed the temple because Caesar had declared Venus the progenitor of his lineage. Today, remnants of the Temple of Venus can be seen on the ground floor of a Renaissance house on Bishop Antun Mahnić Street, now the shop Memento Venerem, while a segment of its presumed altar is displayed in the Perossi House on Vela Placa, now the hospitality venue Volsonis.

Within the city walls, two Glagolitic monuments have been discovered: the Krk Inscription from the 11th century and the Glagolitic inscription on a basin in the sacristy of the Franciscan Monastery. 

The Krk Inscription, written in round Glagolitic script, was found on the corner of the upper facade of a canonical house at Dinka Vitezić Street 11. In 1953, the inscription was removed from the wall and placed inside the house for preservation.  The inscription contains four lines of round Glagolitic script. According to Branko Fučić’s transcription, it documents the construction of an unknown building: Se (ovo) zida Maj opat i Radonja, Rugota, Dobroslav.

The Krk Inscription is among the oldest Glagolitic finds, alongside the Plomin Inscription and the Valun Tablet, and predates the Baška Tablet, which is dated to 1100.

The Frankopan Castle, a fortified residence of the Dukes of Krk, is the only preserved secular medieval monument in the city. It was constructed between the 12th and 16th centuries. The oldest part of the castle, the square Frankopan tower-courtroom, adjacent to the Bishop’s Palace, was completed in 1191, as recorded on a Latin inscription preserved on the lunette above the entrance. The inscription records that the tower was constructed collectively by the municipality during the time of Bishop Ivan of Krk and Dukes Bartol and Vid.
