New Archaeological Discoveries in Galway Bay
#GALWAY BAY NEWS - Archaeologists in Galway Bay have unearthed an extensive tidal weir complex at Barna and a late medieval quay on Mutton Island, The Irish Times reports.
The weir, which is estimated to date from the early Christian period, consists of a granite barrier with channels cut through it, designed to control the flow of water in the adjacent lagoon.
Connemara archaeologist Michael Gibbons suggests that the weir implies a considerable fish stock migrating through the area into the Barna river.
The remains of a large Iron Age fort which overlooks the site may also have given its name to the townland of Knocknacarra, which is now a populous suburb of Galway.
Meanwhile, further east at Mutton Island a medieval quay which predates the current lighthouse quay has been found.
