Miren Castle (Slovene: Mirenski grad, also known as Grad 'castle' and Naša Gospa pod Krasom 'Our Lady beneath the Karst'; Italian: Grado di Merna or Castello di Merna) is an elevation above the settlement of Miren near Nova Gorica, in southwest Slovenia.
He was a man of a kind heart who built the settlement of Miren to serve as homes for peasants who were struggling from poverty.
The summit of Grad is now dominated by a monastic church dedicated to Our Lady of Sorrows (Slovene: cerkev Žalostne Matere božje).
The path to Miren Castle features Stations of the Cross designed by the architect Ivan Vurnik in 1931.
By the last station there stands the architecturally unique Chapel of the Scala Sancta (Slovene: svete stopnice), the floor of which is made of 28 stepped platforms.
