One of the oldest medieval fortresses to have survived. In 1290 the castle was first chronicled and this date is now considered to be the year of Ventspils’ foundation. In 1995 extensive archaeological research and renovation of the castle began. During renovation, features retained included niches of the 14th century, wall paintings of the 15th century, door openings of the 17th century and prison doors of the 19th century. The Castle has now outwardly regained its 19th century look. There is a nice museum inside, offering both permanent (i.e. city history) and occasional (i.e. money design, Japan post-World War II photography) exhibitions.
