The skilful and strict Cardinal Gentilis of Montefiori, delegate of the Pope, imposes a heavy punishment and promises the excommunication of anyone who will marry people of other religions apart from the Catholic one. A great council gathered in Pojon (Bratislava) in 1309. It had been a busy year for the cardinal to whom the Papal seat had given the mission to solve so many important things in the Kingdom, from the excommunication of the Prince of Ardeal, Ladislau, because he wanted to marry his daughter to the son of the King of Serbia – an orthodox – to the confirmation of the bishop of Transylvania as he had been asked by Ulricus, decanus de district de sanctae Ladislao, and by nine other deans.

This is the first document mentioning Laslea, name derived from Saint Ladislau who was the patron of the church. There isn’t any document attesting the presence of a basilica here, but presumably only the belfry was preserved from the old building. The old monument that lasted up to the 19^th century had a pentagonal choir, three naves, and the already mentioned tower had a south-north orientation. The present church doesn’t overlap the plan of the basilica because it has an east-west orientation. There is an inscription mentioning 1456 as the year of construction but most probably it was the year of transformations, as it is the case of other 15^th century basilicas. According to the marks on the belfry it was assumed that the basilica had a barrel vault and a gabled roof, evidence which is given by the traces of gable on the wall. Fragments of the barrel vaulted aisle walls were also preserved. The belfry wasn’t placed on the axle of the church as usual, but towards the south with an open portico in front of the entrance, whose empty spaces were walled in along with the fortification of the tower, accessible now only on the second floor to which the entrance is made from the inside. The five floor tower has narrow battlements and arched openings at the top. The last floor is the protruding defense level which has a hipped roof.

From the fragments of walls which were preserved results that the church was surrounded by a simple curtain wall which wasn’t defended by towers. On the west side the ruins still reach almost five meters and the holes in which the beams of the wall-passage joined were also preserved. A storage room for grains was annexed to the north wall.
