Les Flèches des cathédrales, Metal sculpture near A10 motorway in Forges-les-Bains, France

Les Flèches des cathédrales is a 21-metre, 30-tonne metal sculpture by Georges Saulterre, installed in 1989 beside the A10 at Forges-les-Bains. Tall, narrow, blade-like spikes rise and splay outward from a single base on a grassy slope; the light grey or silver blades are pointed at their tips, some angling upward and others leaning outward, with a cluster of smaller blades near the base. A dark rectangular sign on a post to the left reads "sculpteur" and "Saulterre".

Georges Saulterre made the sculpture in 1989 for the A10 motorway near Forges-les-Bains. Cofiroute acquired the 21-metre, 30-tonne work. In 1998 the Guinness Book of Records listed it as the tallest sculpture made by a man.

The title refers to cathedral spires, though the 21-metre work stands beside the A10 motorway at Forges-les-Bains rather than at any church. Georges Saulterre, who also made Sur la trace des Vikings, took his forms from mineral structures such as quartz and pyrite crystals. A dark sign beside the sculpture reads "sculpteur Saulterre".

The sculpture sits at the departmental border and is clearly visible from the A10, particularly for drivers traveling between Paris and Saint-Arnoult. The installation is best appreciated from the moving vehicle, as it was designed specifically for this viewpoint.

In 1998 the Guinness Book of Records listed it as the tallest sculpture made by man, at 21 metres and 30 tonnes. The work was bought by the motorway operator Cofiroute, which owns the piece standing beside the A10. Its creator Georges Saulterre also made Sur la trace des Vikings.
