The ruins of Brahehus Castle are located 3 km (2 mi) outside of Gränna in Jönköping County in the province of Småland, Sweden.
The rock Brahehus stands on was originally known as "Gudsbacka" or "Grusbacka" and was before the construction of the castle occupied by a small hut.
The plans for a castle on Gudsbacka, chosen for its views of the county, were first conceived by Count Per Brahe the Younger in the 1630s, who intended it as a dower house for his wife, Countess Kristina Katarina Stenbock.
[4] On 29 September 1708, a fire broke out in the nearby village of Uppgränna [sv], which quickly spread to and consumed Brahehus.
[5][8] In 1972, the E4 motorway, with a service area (including, despite objections from the National Heritage Board and the local antiquarian, a petrol station), was opened 50 m (160 ft) from the ruins.
