Chapel of Holy Trinity, Baroque chapel in Rosice, Czech Republic.

The Chapel of Holy Trinity is a Baroque chapel on the Trojice hill at the southern edge of Rosice. Its ground plan is a triangle whose perimeter is formed by six apses: three at the triangle's corners and three set between them. The roof is a regular hexagon, as are the apsidal roofs; the original shingle covering was replaced by sheet metal in the 1930s.

Jiří Rupert Hausperský founded the chapel as a new pilgrimage site in 1697, and it was completed in 1701, when the pilgrimage tradition on the Feast of the Holy Trinity began. It was built with a hermitage on the site of an earlier hornbeam grove. In 1783, during Joseph II's dissolution of religious houses, the nearby Chapel of St. John Nepomuk was demolished, but this chapel survived and only the hermitage was abolished.

Pilgrimages here have been held on Trinity Sunday since the chapel was completed in 1701. The heart of Felicián Julius Hausperský, who commissioned the 1722 Way of the Cross with its 12 stations, was buried in the chapel after his death in 1723.

The chapel stands on Trojice hill at the southern edge of Rosice, not in the centre. It is reached by a Way of the Cross lined with a protected linden avenue, so allow time for the climb.
