The castle in Severin na Kupi is mentioned for the first time in 1558. The Frankopans erected it above the steep bank of the river Kupa, whilst along with the tower the chronicles also mention a wooden castle from the same period. After the death of the last of the Frankopans and the failure of the Zrinski-Frankopan Conspiracy in 1671 this building was also looted and ruined.
The castle gained its current appearance with a renovation in 1803, during the time of Duke Ivan Oršić. It is a two-storey building of a rectangular ground plan, corners reinforced with cylindrical towers and with an interior courtyard and arcade columns. The Chapel of St Florian, located within the castle complex, has small dimensions with an emphasised arched doorway and turret. Alongside the castle is a garden, which is protected and has been declared as a monument of landscape architecture.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
