What is a Celtic dwelling called?

There's no single name for a Celtic dwelling because the Celts were a diverse group of people spread across a vast area. They lived in different types of homes depending on their location, climate, and resources.

Here are some examples:

* Crannóg: A type of fortified lake dwelling found in Ireland, Scotland, and Wales. These structures were built on artificial islands created by piling up stones and logs.

* Roundhouse: A circular dwelling with a conical thatched roof, common in Britain, Ireland, and Gaul. They were usually made of timber and wattle and daub.

* Crib: A small, rectangular dwelling found in mountainous regions of Britain and Ireland. These structures were typically made of stone and were often used as shelters for shepherds and farmers.

* Dun: A fortified settlement, often found in coastal areas of Scotland and Ireland. These structures were usually built on hills and were made of stone.

It's important to note that these are just a few examples of the many types of Celtic dwellings. The specific name of a dwelling would depend on its location and the time period.
