Located near the northern gate of the city, which was historically called Porta Flaminia, it is a significant and popular gathering place with historical and architectural importance. The name "Piazza del Popolo" translates to "People's Square," though it originally referred to the poplars (populus in Latin) that once surrounded the area.

Key features include:

1. Obelisk of Ramesses II: At the center of the square stands an ancient Egyptian obelisk, brought to Rome by Emperor Augustus in 10 BC. It is one of the oldest and tallest obelisks in Rome.

2. Twin Churches: The square is flanked by two nearly identical churches, Santa Maria dei Miracoli and Santa Maria in Montesanto, designed by Carlo Rainaldi. These churches were constructed in the 17th century and serve as prominent landmarks.

3. Santa Maria del Popolo: Located on the northeast corner, this church is known for its stunning art and architecture, including works by Caravaggio, Bernini, and Raphael.

4. Fountains and Statues: The square features several fountains and statues, including the Fountain of Neptune and the Fountain of the Goddess Rome.

5. Historical Significance: The square was historically the main entrance to Rome for travelers coming from the north. Its layout and design have evolved over the centuries, with significant contributions by architects such as Giuseppe Valadier in the early 19th century, who gave the square its current elliptical shape.
