List of prehistoric scheduled monuments in Gwynedd (former Merionethshire) facts for kids

Kids Encyclopedia Facts

Gwynedd is a big, beautiful county in North Wales, full of mountains, farms, and hills. It's like a giant outdoor museum! This area is home to many amazing old sites, especially in the southern part, which used to be called Merionethshire.

Gwynedd has a huge number of these special places, called scheduled monuments. These are important historical sites that are protected by law, meaning no one can dig them up or change them without permission. It's like they have a special shield to keep them safe for future generations!

Because there are so many, we've split them into different lists. This article focuses on the 171 prehistoric sites found in the old Merionethshire area. Prehistoric means they are from a time before written history, like the Stone Age, Bronze Age, and Iron Age.

Many of these sites are burial places, where ancient people were laid to rest. These include things like:

  • Chambered tombs: Stone structures where people were buried.
  • Cairns and mounds: Piles of stones or earth covering burials.
  • Barrows: Large earth mounds, also for burials.

Other sites are domestic, which means they were places where people lived. These often include:

  • Hut circles: The stone foundations of ancient round houses.
  • Enclosures: Areas surrounded by walls or ditches, often protecting homes or farms.

You'll also find defensive sites, which were built to protect communities. These include:

  • Hillforts: Large forts built on hilltops for defense.
  • Promontory forts: Forts built on pieces of land sticking out, often by the coast.

These sites help us understand how people lived, worked, and even fought thousands of years ago! Organizations like Cadw (Welsh Historic Monuments) and RCAHMW help find, protect, and study these incredible pieces of history.
