The historic town centre with the castle complex is well preserved and is protected by law as an urban monument zone.

Hradec nad Moravicí consists of eight municipal parts (in brackets population according to the 2021 census):[2] Hradec nad Moravicí is located about 7 kilometres (4 mi) south of Opava and 23 km (14 mi) west of Ostrava.

The first written mention of Hradec and the local fortress is from 1060, when Bolesław II the Generous' army was defeated here.

[3] After the fortress was damaged by fire in the mid-13th century, King Ottokar II of Bohemia had rebuilt it into an extensive Gothic castle.

[3][4] Hradec was owned by the Czech kings until 1585, when Rudolf II sold it to Kašpar Pruskovský of Pruskov.

Hradec nad Moravicí is connected with Opava by a short railway line of local importance.

In the second half of the 19th century, the complex was extended by the neo-Gothic Red Castle with stables, coach rooms and mural wall.

[9] Silesian Calvary is a pilgrimage site formed by Stations of the Cross from 1764, leading from the town to Kalvárie Hill.
