The northern and western walls are reserved for exhibiting the findings of the Crusade basilica, built in the 12th century. The most interesting are the capitals, some intact and others less so, all magnificent examples of medieval crusade art inspired by the French.
Some architectural parts are also on display, decorated with animals and others with drapes of clothing, which in all likelihood belonged to a larger range of decorations of the entire basilica. The eastern wall also shows three parts of the cornice with inscriptions in Latin, which can be reconstructed as: "Ecce ancilla Domini… concepit de sanctu spirito”. This inscription probably belonged to the cornice placed in the crusade era above the worshipped grotto or on entrance to the church.
The same wall shows the stone with the uncial writing of the 12th century, found in 1966 in the Grotto of the Annunciation, with the Hail Mary in Latin, accompanied by some signs, or coat of arms of unclear identity. The inscription was probably the work of a pilgrim who carved into a stone of the basilica by then in ruins.
