Vipavski Križ is a settlement on a small hill in the Vipava Valley in the Municipality of Ajdovščina in the Littoral region of Slovenia. There is evidence of habitation on the hill in the pre-Roman period. The settlement was first mentioned in written documents dating to the 13th century. The houses in the village are clustered inside a defence wall around a castle from the late 15th century. It was built to protect the residents against Ottoman raids. In 1532 Vipavski Križ was declared a town. In 1636 a Capuchin monastery with a rich library was founded in the town and it is now open to visitors.
