The only masonry buildings were the castle, the mosques and the courtain surrounding the Angevin Fortress in the southern part of the city.

János Pálffy and his cavalry settled to the south of the fortress, with the purpose of blocking any Ottoman attempts to fetch reinforcements.

Eugene of Savoy set up his General Staff, infantry, artillery and some cavalry to the northern part of the fortress, completely surrounding it.
