Yvignac-la-Tour (in French pronounced as /iviɲak la tuʁ/; Breton: Ivinieg) is a commune in the Côtes-d'Armor department of the region in Brittany in northwestern France.
One of Yvignac's most prominent landmarks, reflected in the town's name, is the tall tower of its church. This tower is not a steeple, tapering to a point, but has a flat roof. Also inside the church at the back entrance is a large old coffin, and a wall. This wall is split into three sections, the top sowing a grail, possibly being the Holy Grail. The bottom left is a shield and sword, on the shield is a cross, this could be a major artifact, we know that this could point to the Knights Templars. the last bit of the shield was faded.
The inhabitants of Yvignac-la-Tour are known in French as yvignacais.
