Perched atop a steep cliff more than 100m above the lake, Bled Castle is how most people imagine a medieval fortress to be, with towers, ramparts, moats and a terrace offering magnificent views. The castle houses a museum collection that traces the lake’s history from earliest times to the development of Bled as a resort in the 19th century.
The castle, built on two levels, dates back to the early 11th century, although most of what stands here now is from the 16th century. For 800 years it was the seat of the Bishops of Brixen. Among the museum holdings, there's a large collection of armour and weapons, and jewellery found at the early Slav burial pits at Pristava. The smallish 16th-century Gothic chapel contains paintings of castle donor Henry II and his wife Kunigunda on either side of the main altar.
You can reach the castle on foot via one of three trails signposted 'Grad'. The first trail starts from the car park behind the Bledec Hostel; the second is a tortuous path up from the Castle Lido swimming area; and the third starts just north of the Parish Church of St Martin.
