The Kieniewicz family chapel was built around 1880, but its author is unknown. All we know is that the creator of the unpreserved altar relief is Pius Welonski. The chapel is located in the Campo Verano cemetery, in the Caracciolo ramp (exact address: piazzale del Verano 1, Roma). It is built of brick, and the architectural details and sculptural decoration are made of marble.

In the chapel, the following are mentioned on the panels:
. Hieronim Kieniewicz (1797-1884)
Katarzyna Horwatt née Kieniewicz (1807-1891)
Kamilla Kieniewicz née Mikulska (1828-1904), buried in Kraków.
