Of course patterns or patrons still exist. Look at somewhere like Gleanncholmcille where there is a circular pilgramage of over 46 stations, some of which are wells, megalithic tombs, christianized standing stones, rock outcrops etc.

If that doesn't constitute an active ritual landscape I don't know what does. In the UK you've lost all that because the Proddies don't go in for such stuff, but go to a good old Catholic country and you will find it.

Lugnassa festivals only really died out in the 1950s. over 200 of these were held on mountain tops in Ireland exvery year, usually with processions up the hill to a cairn or stone. There is still one big one (very commercialised now) in county Antrim every year.
