Church of Our Lady beneath the Chain

The Church of Our Lady Beneath the Chain stands on Malá Strana in Prague, right on Grand Priory Square (Velkopřevorské náměstí), and has belonged to the same knightly order for close to nine centuries — today's Knights of Malta.

Who founded the church, and when?

The Knights Hospitaller settled on the left bank of the Vltava in the second half of the 12th century and built their commandery there, a local seat for managing property and receiving travellers. Their first church, a Romanesque basilica, was consecrated in 1182, right next to the bridgehead of the old Judith Bridge, predecessor to Charles Bridge. Looking after that river crossing was part of the order's job from the start.

Where does the name "Beneath the Chain" come from?

The name points to a chain once used either to secure the gate of the commandery, or — the more likely explanation — to close off the river near the bridge, stopping boats from slipping past Prague without paying the toll. Since the Hospitallers were responsible for the crossing, controlling river traffic fell naturally under their care.

Why does the church have only two towers, as if it were never finished?

Early in the 14th century, after the Knights Templar were dissolved, the Hospitallers inherited part of their property, and selling it off funded a far more ambitious rebuilding project. The plan called for a grand three-aisle Gothic basilica, work associated with the circle of Peter Parler's workshop, the same builders behind St Vitus Cathedral. The scheme proved too bold: only the choir, the sacristy, and two front towers linked by an entrance hall were ever completed, while the rest of the nave never rose. Those two towers, framing the square in front of the church today, are its most recognisable feature — what's left of a design that was never carried through.

What changed in later centuries?

In the 17th century the interior and presbytery were reworked in the Baroque style, under architects Carlo Lurago and Giovanni Battista Spinetti. The main altar painting dates from this period too — a work by Karel Škréta showing the Virgin Mary blessing the Knights of Malta, a reference to the Christian naval victory at Lepanto. Most of the sculptural decoration is the work of Jan Petr Wenda.

Who owns the church today, and can you visit?

The building still belongs to the Sovereign Military Order of Malta and serves as the monastery church of its Czech Grand Priory — effectively the order's administrative and spiritual home in the Czech Republic. Visits inside are mostly by appointment or just before Mass, though anyone can look through the locked grille gate at any time. Mass is held on Sundays at 10:00 and Tuesdays at 17:30.
