Rize Castle (Rize Kalesi) is a significant medieval fortress offering a historical glimpse into the city of Rize in northeastern Turkey. Situated on a prominent hill approximately 150 meters above sea level, the castle commands a panoramic view over the city center and the Black Sea coast.
Its origins are traced back to the Byzantine era, with the inner citadel generally believed to have been constructed during the reign of Emperor Justinian I in the 6th century AD. Architectural comparisons suggest the outer, lower castle section was added later, possibly in the 13th or 14th century, when Rize was part of the Empire of Trebizond.
The fortification consists of two parts: the inner citadel and the lower castle, encircled by substantial walls built from ashlar and mortar. Though now partly ruined and partially encroached upon by modern concrete buildings, the southern sections underwent restoration in 1989, with further restoration projects launched later. Today, the interior of the upper citadel has been transformed into a small public park, complete with a tearoom, inviting visitors to relax while soaking in the historical atmosphere and the extensive city views.
