 The heads of the three executed men were displayed on the corners of St James Cavalier, but were removed soon after Emmanuel de Rohan-Polduc was elected Grand Master in November of the same year.After taking control of Malta in the beginning of the 19th century, the British converted the cavalier into an officers' mess, a place where soldiers could socialize.Some modifications were made to the structure at this point, including replacing the ramp leading to the roof by a staircase, and increasing the number of rooms by building an arched ceiling within the ground floor room, therefore creating two stories where there had been only one.
