Embarquez dans un bateau éco-lodge et partez à la découverte de l’histoire et de la culture d’un lieu refuge, « Ganvié ».

I asked my client for a bit of background, and this was her response ""Lieu refuge" because Ganvié, a village built on the lake was founded by people fleeing the slave raids. They took refuge on the lake".

I am unsure of an appropriate term to use here. Can anyone help?
