Brochs can be found around Scotland, but most are in Caithness
Work has started on upgrading a museum to change it from the Northlands Viking Centre to the Caithness Broch Centre.
The building's new name reflects the record number of the 2,000-year-old stone towers found in the area.
Due to open in spring, the centre will document and display artefacts from Caithness's past, including Vikings.
Highland Council said the area has more brochs per square mile than any other part of Scotland. It has also seen more excavations of the towers.
Caithness Archaeological Trust has led the project which involves the local authority and National Museums of Scotland.
Meanwhile, pupils from Keiss Primary School and their teachers have been working closely with broch excavations and class teacher Rhona Macpherson has been involved in the development of a teachers' pack about the brochs.
