The enormous Renaissance-style Podčetrtek Castle, atop a 355m-high hill to the northwest of town, went up some time in the mid-16th century but was badly damaged by an earthquake in 1974. It's not open to the public but offers stunning views. To get here, walk north along Trška cesta and then west on Cesta na Grad for about 1.5km.
