Abbaye Saint-Martin d'Epernay, Medieval abbey ruins in Épernay, France.

The surviving portal of the Abbaye Saint-Martin d'Épernay is a tall, freestanding ruin of pale beige stone in a classical style. Its left side centers on a large arched portal flanked by paired columns and topped by a triangular pediment with carved figures; a smaller arched opening stands behind. To the right, the wall curves outward around a small niche with columns and a miniature pediment, and a dark rectangular plaque is mounted low on the wall. The base lies in a flower bed with a sign reading "EPERNAY".

The abbey was founded in 1032 and underwent several transformations until 1790, when the French Revolution led to its closure and partial destruction. The losses during this period marked the end of its role as a religious center.

The lateral portal, dated 1540 on its pediment, is called the Saint-Martin portal because of the equestrian statue of Saint Martin carved in its niche, probably by Pierre Jacques. In 1566 the prior François Vautrin, a painter, had begun decorating the cloister with historical paintings.

The surviving portal stands outdoors in a flower bed marked with an "EPERNAY" sign, so it can be viewed at any time from the surrounding public space. The carved pediment and the niche holding the equestrian statue of Saint Martin sit high on the facade; step back to read them. The dark plaque low on the wall carries the monument's identification.

The portal's triangular pediment carries a carved equestrian statue of Saint Martin in its niche; the 1540 date is inscribed on the pediment. The portal is attributed to the sculptor Pierre Jacques. The dark plaque low on the wall marks the monument today.
