St Ladislaus' Church was founded by King Casimir the Great to redress the death of a priest named Baryczka. The temple was built on the site of a wooden church. The church was burned and rebuilt many times. During the last renovation works, in the 1940s, in the centre of the aisle the remains of the pillars were found, which helped to reconstruct the church with two aisles and the vault forming two five-pointed stars. St Ladislaus' Church is a splendid exemple of the early Gothic style in the churches founded by Casimir the Great.
The synagogue dating from the middle of the 16th century is situated in the North side of Szydlow. The stucco and painting decoration dating back to the 17th century, has still been preserved. The building was erected on square ground plan. In earlier times it was provided with a protected hiproof. Buttresses placed above the arched windows and the attic as well, made almost a little fortress of that synagogue. An old polychromy and some dates have been preserved under the plasters. An altar for the Pentateuch rolls called "Uzen Kodeusz" was in the East wall of the synagogue.
Little Treasury transformed in the middle of the 16th century from an old round tower (a two - storied building with a cellar). The West and North walls in their lower parts were primarily sunk into the town walls. Nowadays, it comprises the Museum of the Region. The latter has three expositions: that of natural history aims at explaining the geological structure of the region of the South border of the Holy Cross Mountains, that constitutes a separate structural unit, where Szydlow is localized; the archaeological exposition gives a brief presentation of the beginning of the settlement and the development of the latter in the area of Szydlow its environments - from the appearance of the first groups of population up to the beginning of the Polish imperium; the historical exposition presents the history of Szydlow from the time of its beginning up to the World War II. From the relics of great historical and museum value there are to be enumerated the products of manufacture of the local guilds, such as: locks and padlocks made of iron, fragments of ceramic (Gothic bricks called "palcowki" i.e. hand manufactured ones), pieces of modern vessels and stove tiles. Some militaria dating from various periods are also exposed.
The southern wall of Little Treasury is decorated by an antique sun-dial.
Althought the authorities apparently know that the town has many attractions for tourist, Szydlow is not well prepared for their visits. I mean all the relics and monuments are quite well descript and in the town you can easy find the maps with important places, but there is (probably) no single hotel in the town. The same is with eating - in Szydlow there are only shops and few bars (rather for local lovers of beer than for tourists), but no restaurant, where you can have a good meal.
