Origin and history

Bastion No. 1 is a preserved element of Thiers' enclosure, built between 1841 and 1845 during the reign of Louis-Philippe. This fortification, designed to protect Paris, was dismantled in 1919, but this bastion, located in the 12th arrondissement, escaped destruction. It illustrates 19th-century military architecture and its defensive role in Parisian urban history.

Located below Poniatowski Boulevard, near Bercy wharf, the bastion is isolated by Robert Etlin Street. Its access is via a staircase descending from the boulevard, before the National Bridge. This strategic positioning, close to the Seine, reflects its integration into the overall defensive system of the enclosure.

The bastion was listed as historic monuments on May 21, 1970, recognizing its heritage value. Unlike the majority of the remains of Thiers' enclosure, demolished after World War I, this bastion remains as a rare material testimony of this period. Today, it belongs to the municipality of Paris and remains a point of local historical interest.

The enclosure of Thiers, of which it is a vestige, deeply marked the Parisian landscape. Its construction met geopolitical and military concerns, while its subsequent destruction symbolized the evolution of urban needs. Bastion No. 1, with other preserved elements such as Bastion No. 44 or No. 45, provides a concrete overview of this history.

Available sources, including Wikipedia and Monumentum, confirm its status as a protected monument and its precise location at 117 bis boulevard Poniatowski.
