The Quirinal Hill is one of the Seven Hills of Rome and the largest. It is located at the north-east of the city center. It is the location of the official residence of the Italian head of state, who resides in the Quirinal Palace; by metonymy "the Quirinal" has come to stand for the Italian president. The Quirinal Palace has an extension of 1.2 million square feet.

It was originally part of a group of hills that included Collis Latiaris, Mucialis, Salutaris. These are now lost due to building in the 16th century and later.

According to Roman legend, the Quirinal Hill was the site of a small village of the Sabines, and king Titus Tatius would have lived there after the peace between Romans and Sabines. These Sabines had erected altars in the honour of their god Quirinus (naming the hill by this god).
