The Loreto Shrine is a baroque pilgrimage complex on Loretan Square in Hradčany, a short walk from Prague Castle. The centrepiece is the Santa Casa — a replica of the Virgin Mary's house in Nazareth, supposedly transported by angels to Loreto in Italy, and then copied all over Catholic Europe as a pilgrimage site. Prague's version, encased in a later baroque cloister and church, dates from 1626.
The interior cloister walk contains chapels with elaborate decorations; the Treasury above holds the Diamond Monstrance, one of the most extravagant religious objects in Central Europe. The carillon in the tower plays a Marian hymn every hour. Much quieter than the castle complex nearby, and genuinely fascinating for those interested in baroque devotional art.
