Hronov is a small town with a little over 6500 residents situated on a wide Broumov Upland, on the river Metuje, at the altitude of 360 m. The first written record about the settlement comes from 1359, but historical accounts justify the theory that it was probably established a century before by Hron, the lord of Náchod castle, who in mid-13th century started colonizing the uninhabited parts of his domain.
On a small hill a little above the centre stands All Saints' church. The originally gothic structure from 1359 was destroyed during the Thirty-Year War. Only the chancel survived and it was later long used as a chapel. In 1713-17 the remnants of the church were rebuilt in the baroque style. The former chancel was given baroque windows and the nave was added.
By the side entrance we can see the grave of Antonín Knahl, a clockmaker and musician, who was buried here by his wife Justynka. Knahl's house, marked with a memorial plaque, stands in the street leaving the town square in the direction of Police nad Metují.
