The Knights' House (No. 6), from the 14th century, testifies to Kraków's Gothic heritage and remains church property. The Górka Palace (No. 24), from the second half of the 16th century, was transformed in the Mannerist style. Interestingly, it once housed a telegraph office, which gave rise to its name.
