The ruin lies at 450 m above sea level. M. across the valley of the Seez on a rock spur steeply sloping to the north and east above the old trade route from Zurich to the Graubünden passes. Several finds from different eras indicate that Grapplang was already settled in prehistoric times and in the Bronze Age. The castle was built between 1100 and 1200.

Gräpplang Castle, also called Castrum Flumius, is the ruin of a spur castle near Flums in the canton of St. Gallen in southeastern Switzerland. The name Groppa lunga means long rock. The Romansh origin of the word suggests that this language was widespread in this area.
