Behind the church of St Mary, the Benedictine sisters guard a hoard of medieval gold- and silverwork: saints' arms and skulls cased in jewelled metal, illuminated manuscripts, painted panels. For centuries they spirited it into hiding whenever armies came; today it glows in hushed, dim rooms as one of Croatia's great collections of sacred art.
It's small and easy to miss next to St Mary's, but it's the most precious room in Zadar.
A small next-step selection from the same city.
