Gärdslösa Church, Medieval Lutheran church in Borgholm Municipality, Sweden.

Gärdslösa Church is a whitewashed stone church with a square west tower topped by a pale green dome and lantern, a steep orange-red tiled roof, and a south entrance porch with a matching gable. It has a nave, a choir of nearly equal width with a crow-stepped gable, and two transepts. The north transept's exposed, colour-shifting masonry contrasts with the whitewashed walls.

According to tradition, the church was inaugurated in 1138; its oldest parts are the western nave and the slightly later tower foundation. In the mid-13th century it was enlarged with transepts and vaulted by the Gärdslösa Master, and the choir was rebuilt in stages by the Gotland master stonemason Ronensis. The sacristy followed, and the tower lantern was added in 1845.

The 1498 wall paintings are signed by Magnus Ingelsson, while those of 1642 are attributed to Peter Bundi. The pulpit dates from 1666 and was made or at least painted by Jörgen Bundi. A model of the warship Nyckeln, dated 1682, hangs in the church as a votive ship.

The church remains active and serves regular worship services, so visitors should plan their activities according to the church calendar. The place functions as a living religious community space, so appropriate behavior and respect for ongoing activities is important.

In 1964 the church hosted the wedding ceremony of Swedish Princess Margaretha and John Ambler, bringing it international attention. This royal event gave the location a notable place in modern Swedish royal family history.
