The street chapel of St. John of Nepomuk was built in 1727 on the initiative of Abbot Ludwik Bauch. There is an entrance on the south side, but the original Baroque interior has been lost. The building is covered with a dome with a lantern, and below the dome are windows that illuminate the interior from above.
The Chapel of St. John of Nepomuk, built in 1727, is a central structure with an entrance on the south. The interior is topped by a dome with a lantern. Above the entrance is a cartouche with the monogram of the founder, Abbot Ludwik Bauch, and the date of construction – "LAL/1727." Just below the dome are oval windows, illuminating the chapel interior from above. The dome is topped by a small lantern, covered with a domed roof. The Baroque interior decoration of the chapel has not survived.
