Skopje Fortress was rebuilt several times before it was destroyed by the 1963 earthquake. Since then, it has been restored to its medieval appearance. It is the only medieval monument in Skopje, but several churches located around the city illustrate the Vardar architectural school which flourished around 1300. Among these churches are the ones around Matka Canyon (St Nicholas, St Andrew and Matka churches). The church of St. Panteleimon in Gorno Nerezi dates from the 12th century. Its expressive frescoes anticipate the Italian primitives.
