Fort de Meyzieu, Military fortress in Meyzieu, France

Fort de Meyzieu is a ruined military fort built from 1893 to 1896 in Meyzieu. A tall curving retaining wall of rough grey stone and concrete, overgrown with ivy, runs beside a dirt path; a metal railing tops it, and a row of rounded arch-shaped openings is set into the wall face. The ruins now hold a health trail.

The fort was built in the late 1800s as part of Lyon's defensive system against potential invaders. Its construction reflects how military design adapted to advances in weapon technology of that period.

The fort now serves as a public gathering place where locals walk, exercise, and spend time with family. This transformation shows how historical sites become woven into everyday community life.

The ruins stand in Meyzieu, bought by the commune in 1979, and are reached on foot; a fitness trail now runs through the site. The surviving rampart is a curving wall of rough grey stone and concrete, topped by a metal railing, with a row of arch-shaped openings set into its face. A dirt path runs along its base, below a bank of low vegetation.

Built after the invention of melinite, the fort had neither powder magazines nor artillery firing platforms, a departure from earlier Séré de Rivières works. The Germans used it as an ammunition depot and destroyed it in 1944; the town of Meyzieu bought the land in 1979.
