The monastery church, built in colored stucco and marble, is one of the most lavishly decorated in Lower Bavaria.
It was designed and built between 1726 and 1740 by the Munich architect and master-builder Johann Michael Fischer (1727–28) and the brothers Cosmas Damian Asam and Egid Quirin Asam.

The nave is large, bright and spacious, with a 22 metres (72 ft) high ceiling.

The Asam brothers created a throne room in honor of God, a  "theatrum sacrum".

Cosmas Damian Asam, a brilliant painter, created the wonderful frescoes in the church.

His brother Egid Quirin Asam filled the church interior with sculptures and ornaments, notably the impressive high altar.

The altarpiece represents Saint Margaret set within a pagan environment, with a statue of Venus in a temple behind her.

The church is considered a masterpiece of late baroque Bavarian church architecture.

In 1983 the church became the Minor Basilica of St. Margaret, known as the Asambasilika.
