(1748) The Alicorni, an
Albanian family, had escaped from their homeland during the reign of
Pope Pius II (r. 1458–64), because of the
Ottoman advance in their country. They settled first in
Milan, then in
Pavia,
Forlì, and finally in Rome. The palace originally had its main facade along the
Borgo Vecchio road. Trajano Alicorni left two sons, Giovanni Battista and Fabio, who were both appointed knights by the Pope. Some months later the prelate died, leaving the palace to his heirs, who sold it again to others who neglected the building, which fell into disrepair. In 1667, the erection of
the Colonnades of St. Peter's square by
Gian Lorenzo Bernini made it necessary to pull down the last block of houses ("isola") in front of the new square: this was named "isola del Priorato", since one of the buildings hosted the
Priory of
the knights of Rhodes. Until 1850, the palace was the seat of the Roman "Guardia civica" (in that year merged with another
militia to form the
Palatine Guard), thence it was named "Palazzo della Gran Guardia". In 1860, other edifices were erected near the palace, incorporating the rear lane and choking the building. then became for many years a hotel, the "Hotel Pensione Alicorni". As of 2015 the building hosts the UCID ("Unione Cristiana Imprenditori Dirigenti"), an association of catholic
entrepreneurs. ==Description==
