Sure thing! In Madeira they have many ancient aquaducts originally estabilished by the Moors:

Ancient water management is a fascinating topic.

The qanats in the middle-east, and north africa are particularly interesting. They are underground water conduits and sources dug by human muscles alone.

Madeira was initially settled by the Portuguese in the 15th century, 200 years after the end of the Portuguese Reconquista, so it's quite a stretch to claim that the "levadas" were "established by the Moors", even if they initially brought the technology to Iberia.

The moors were never in madeira.

The island chain was empty by the time the portuguese arrived.

I really need to comment, even if others said the same thing.

There were no moors in Madeira.

hmm. You and others are totally right. I miss-read my own source. Sorry about that!
