Today, the Romanesque rotunda is a presbytery of St. John the Baptist Church, which is the effect of a rebuilding from 1627. The scientists used to claim that it is an 11th-century building, probably because of the thickness of its walls, which is between 1 and 1,15 m. Nowadays, after thorough archeological  research from the 70s of the 20th C., we know that the Grzegorzewice rotunda was built on the break of the 13th and 14th C. It was founded by Grzegorz Nawoj, of the Hatchet coat of arms - the owner of Grzegorzewice. The rotunda had been arranged on a traditional plan of a circle with an apse on its eastern side. Its walls, made from the local dressed sandstone, have been preserved till the present. Moreover, the building has original window openings, among which there is a very interesting round window with a tracery.
Above the door of the church there is an inscription “1627”, which marks the year when the nave was built. In the baroque inside there is a stone baptismal font from the 14th C. and a monument with an inscription “ Here lies Onufry Chościak Popiel, the castellan of Sandomierz, the National Cavalry captain, the marshall of the confederation in 1812. Died on the 29th of Nov. 1826 at the age of 58.” What is more, in the sacristy there are the relics of St. Stanisław Kostka and the wood from the Holy Cross.

It is worthwhile to come to Grzegorzewice, located in the landscape of the Świętokrzyskie forests, as the place is really picturesque.
