Derrynaflan

Derrynaflan is an island of dry ground in Littleton Bog, and there was a monastery on it. What survives is a medieval church with the east, north, and south chancel walls standing and five windows in them, the foundations of a nave, a ring barrow, and a cemetery.

On February 17, 1980, Michael Webb and his son went onto the island with a metal detector. They had implied permission to walk the land. They had none to dig it, and the site was already under a preservation order.

What came out was a silver chalice, a composite silver paten, a hoop that may be a stand for it, a liturgical strainer, and a bronze basin that had been turned upside down over the rest of it. They told nobody for three weeks.

The case

Sotheby's valued the hoard at IR£5 to 6 million. The Webbs handed it to the National Museum on the understanding that they would be treated fairly, then sued when they judged they had not been.

The High Court found in 1986 that the vessels belonged to the finders. The Supreme Court reversed that in 1987. Webb v Ireland held that the medieval royal prerogative of treasure trove had never validly carried over into Irish law after 1922, so the state could not claim the hoard the way a crown would have. The court awarded the state ownership on other grounds and gave the Webbs IR£50,000.

The Oireachtas closed the gap that same year with the National Monuments (Amendment) Act 1987, which vested archaeological objects with no known owner in the state and restricted the use of detection devices.

What is still in the bog

Nobody knows who buried the vessels, or when, or why they were never lifted again. The usual reading is that they were hidden during a raid, which would put the burial centuries later than the objects were made.

The island itself has never been excavated.

The basin. The bronze basin had been inverted over the other four objects. That is an act of protection rather than a discard, and it is the strongest single indication that whoever put the hoard in the ground expected to come back for it.

The date gap. The vessels are 8th and 9th century work. The burial is undated. If they were concealed during a raid, the deposit could be centuries younger than the objects themselves, which is why nobody will put a year on it.

The preservation order. The site was already legally protected when the detector went over it. That single fact is what the entire court case turned on, and it is the reason Irish detecting law reads the way it does today.

The hoard is not here. The chalice, paten, strainer, and basin are on permanent display at the National Museum of Ireland on Kildare Street in Dublin, where admission is free, so seeing the objects and standing where they came out of the ground are two separate trips.

The Littleton Labyrinth trail opened in June 2025, a Tipperary County Council and Bord na Mona project running along a disused bog railway from Loch Doire Bhile to the island. Before that the approach was a walk across worked-out peat with no marked route.

There is nothing at the site itself: no interpretation, no facilities, and no supervision.
