Palazzolo (Rome)

[2] The toponym comes from some Roman ruins located on the hill, called "Palatiolum Neronis", because they are believed to be the remains of a small palace owned by Nero.

[4] The Palatiolum, on whose slopes in the Middle Ages extended the two settlements - the latter fortified - of the Schola Frisiorum (for the frisian pilgrims) and of the Burgus Saxonum (for the Saxon pilgrims),[3] is mentioned for the first time in 1053, when it is cited a "fundum quod vocatur palatiolum" (Latin: a farm which is named little palace).

[2][3] The classical Roman structures were fortified on this occasion by Holy Roman Emperor Henry IV of Germany, who left a garrison of four hundred knights commanded by Ulrich of Godesheim.

[5][6] During the Middle Ages on the hill stood the church of Santa Maria in palazzolo.

[7][3] Until the end of the nineteenth century the hill was also called by the populace "la palazzina", because there lay a small villa (Italian: palazzina), outbuilding of the Santa Maria della Pietà psychiatric hospital.
