The High Castle is proximate to the centre of Lviv (see picture), formerly being surrounded by a fortification wall.

Before the castle was built, there were certainly defensive structures in Lviv, but their shape and exact location are unknown.

[4] According to chronicler Jan Długosz in 1340, when Lviv was captured by Casimir III of Poland, the king ordered city's fortifications to be dismantled.

[7] Casimir III built a new town on the Poltva River and granted it a Magdeburg rights in 1356.

In 1537, the castle witnessed a rebellion known as the Chicken War against Polish king Sigismund I the Old and his wife Bona Sforza.

In the times of Khmelnytsky Uprising it was taken by Cossack forces of Colonel Maksym Kryvonis in October 1648.
