Between a tiny Ceredigion village and the sea lies an area of flat land, bordered by the rivers Peris and Cledan.
On maps, it's called Morfa Esgob (Bishop's Land).
It's strangely divided into long strips.

This land is ancient.

They call it Lleiniau—the Llanon Slangs.

The Morfa Esgob name derives from the fact that the land was once owned by the Diocese of St Davids.

Compared to the steep, thin-soiled hillsides, it's well-drained and quick to warm in spring.
Nowadays the land is mainly grazed, but maps and landscape hint at a complex history.
The 1840s parish tithe map reveals hundreds of interlocking "slangs" – narrow strips of farmland of a size that could be managed by a single household.

Looked at from the ground, you'd struggle to notice the delineation.

But from the sky, the evidence is palpable.
The slangs are often termed "pre-19th century" – the date of the first formal survey, but church ownership is recorded in the 1300s.
However, they're almost certainly medieval… or older.

The footpaths are visibly ancient, hinting at centuries of daily treks from home to slang.
But there's a primeval history here.

At Llanon's seaward edge, the slangs are being consumed by erosion, creating a precarious cliff.
And from the beach, water-rounded pebbles are visible in the soil, betraying Morfa Esgob's origins - a time when great glaciers covered Wales.
From the minute to the massive, from the geological to the golden, there are so many more tales of secret Welsh treasures.

I'm compiling as many as I can find in a "Secrets of Wales" thread collection.
