Thérouanne was the capital of the Gallic tribe known as the ‘Morins’. The town was conquered by Julius Caesar. In the Middle Ages, it was the seat of an important bishopric stretching from the Canche to the Yser. It was completely destroyed following the siege by Charles V’s imperial army in 1553, as it was a French enclave.

A lovely walk, with glorious sunshine. The only downside was the final stretch through the town, but apart from that, it was a real treat for the eyes!

A lovely walk with no trouble finding my way; I only followed the .gpx route when in doubt.
And the sunshine was brilliant, too.
The distance was exactly as stated.
Thanks for the information.
