The historian Paul Kläui leans, in addition to imagery, to the Jahrzeitbuch of 1469–1473, and to the comparable ground plan of the church of Oberwinterthur.

Accessible via a monumental staircase, the transverse church [de] has a massive portico of four columns in Tuscan order and an upstream buttress.

[3] The interior of the church is a transverse sermon hall with a large underground gallery and a marble baptismal font at the intersection of the aisles.

Corinthian pilasters and a friezed entablature dominate its interior, as well as three articulated ceiling stucco cartridges in classical design.

The pipe organ and Steinway & Sons piano B-211 in the gallery were installed by Orgelbau Goll Luzern in 1963, and revised in 1984, 1997 and 2009.

The church was considered as a part of the so-called "Laubishof" estate that possibly was located at the nearby plateau where the Uster Castle is situated.

Among many other transfers of lands and goods, on 25 April 1448 Beringer von Landemberg von Griffensee confirmed with permission of his sons Hug and Beringer dem Jungen that at the place where all his ancestors have been buried, money, goods and lands were given to the Uster church as a benefice.

[9] In 1473 the church comrades, based on an older Jahrzeitbuch (Latin: libri anniversariorum) which now is lost, created a new issue being among the best preserved late medieval pastoral books of the Canton of Zürich.
