The Opatów Gate is the last surviving medieval gate in Sandomierz's fortifications — a 14th-century tower that once formed part of a ring of defensive walls around the Old Town. It stands at the northern edge of the historic centre, on the road that leads down from the hilltop town toward the Vistula lowlands below.
The gate can be climbed for panoramic views over the Vistula valley and the surrounding countryside. The loess escarpments that give Sandomierz its elevated position are especially visible from here, as is the patchwork of vineyards on the south-facing slopes across the river. A small exhibition inside covers the town's medieval fortifications.
