Holy Trinity church, Gothic Revival church in Arco, Italy

Holy Trinity church blends Gothic Revival and Jugendstil features in its exterior and interior design. The facade displays pointed arches and curved decorative lines, while the interior holds ornamental details and religious artworks.

Built for Arco's German-speaking Protestant spa visitors, the church was designed by Hamburg architect Heinrich Fricke. The foundation stone was laid on 31 March 1897, and it was consecrated on 18 February 1900. Requisitioned and damaged in World War I, it was rented to the Catholic parish in 1935 and used by them until 1971. The Lutheran congregation returned in 1970–72.

The church is the only Evangelical Lutheran church in the province of Trento. Lutheran services began in Arco in 1878, cared for by the Christuskirche in Meran, and from 1885 a Frankfurt association sent clergy for the spa season. Since 2021 the building has also hosted cultural events.

The church stands on the southern edge of Arco, a few hundred metres from the former Arco station of the Mori–Arco–Riva local railway. It is used for concerts and cultural events by agreement with the municipality, so opening times vary; check locally before visiting. The interior is a single aisle with wooden furnishings by the Colli brothers of Innsbruck.

The combination of pointed medieval arches with flowing Art Nouveau curves creates a rare architectural mix that was unusual for its time and place. This fusion shows how different artistic movements overlapped as designers sought to unite historical and contemporary styles.
