Arco delle Campane, City gate and arch near Saint Peter's Square, Vatican City.

The Arco delle Campane is a classical gateway on the left side of Saint Peter's Basilica, built with traditional stone masonry and arched structures. It serves as a primary entrance to Vatican City and connects the public square area with the interior spaces of the sacred grounds.

The Arco delle Campane is one of the three gates and five entry points into Vatican City, standing on the Vatican–Italy border to the left of St. Peter's Basilica. The sources record no construction date, builder or link to the 17th-century redesign of the square, so its history is documented only by this position at the boundary.

The name references the bell chamber located directly above it, from which the bells of Saint Peter's Basilica ring out across Vatican City. Visitors can hear these bells sound when approaching the gate and experience this acoustic mark of daily life in the Vatican.

This entrance is typically not fully accessible to the public as it is closely monitored by security personnel who permit only authorized persons to pass through. Visitors should use the main access to Saint Peter's Square and view the arch from the outer plaza area.

The Arco delle Campane is one of only five points through which one can enter Vatican City, and one of its three gates. It stands to the left of St. Peter's Basilica, on the border between Vatican City and Italy.
