The painting depicts an interior of a Gothic church, by Pieter Neefs the Younger (1620–after 1675), a Flemish painter specializing in representations of 17th-century ecclesiastical interiors. The composition based on a precise linear perspective leads the eye towards the main altar, around which the faithful and clergy participating in the liturgy are gathered.

The painting was made in oil technique on board, without a visible signature. The upper part of the composition has been cropped, resulting in the loss of the original format and probably also the author's signature.

The work represents the mature style of Pieter Neefs the Younger - precise rendering of space, controlled light and realistic depiction of architecture, characteristic of the Antwerp school. Paintings of almost identical composition appear in several well-known collections and collections - including the Szépművészeti Múzeum (Museum of Fine Arts) in Budapest and a Sotheby's auction (2021).

It is worth mentioning that works from this series are also sometimes attributed to Pieter Neefs the Elder (c. 1578-1656), confirming the strong stylistic affinity between the works of father and son.
