An open day will be held at the medieval chapel of the Annunciation at Ħal Millieri in Żurrieq to celebrate the Feast of the Annunciation next Sunday.

The chapel, which holds a rare cycle of medieval frescoes in a unique rural setting, will be open to the public from 9 a.m. to 6 p.m.

The event is being organised by Din l-Art Ħelwa.

Mass will be celebrated at 10 a.m., followed by the blessing of the adjoining churchyards.

The chapel is held in trust by Din l-Art Ħelwa and two guided tours of the site will be offered on the day at 11.15 a.m. and 3.15 p.m.

Admission is free but any donations collected will be dedicated to the upkeep and maintenance of this historic site.

The chapel dates to around 1450 but excavations have shown it to have been built over the site of an earlier, possibly 13th century chapel, and a much older late-Roman rural complex.

The chapel is best known for its medieval architectural elements and the unique set of frescoes which adorn its side walls between the springing of the arches.
