In this thesis, an attempt is made to summarize the previous archeological research associated with two feature types in Sweden made from fire-cracked stones: the fire-cracked stone embankment and the burnt mound. The ?lim is to study how trends in interpretation and focus have developed. Furthermore, a compilation of ten excavation reports of burnt mounds between 2002 and 2013 is presented with the aim of determining their purpose, their usage of methods in general and petrography. The result of the summary confirms that there are discernable trends present and the result from the compilation of reports show that the larger scope is prioritized and that there are a number of commonly used methods, but that petrography is not among them.

Det finns två huvudområden för hällristningar i Västmanlands län med nära relation till de forntida strandlinjerna. I båda dessa områden finns det fornborgar som hittills inte har daterats. Syftet är att datera Näsborgen och Kastena Skans i östra och västra Västmanland genom att använda geografiska informationssystemet QGIS och forntida strandlinjedata hämtad från Sveriges Geologiska Undersökning (SGU). Dessutom betraktas fornborgarna ur ett landskapsperspektiv och deras relation till hällristningar och skärvstenshögar som styrker en bronsåldersdatering för dessa fornborgar. Analysen använder tidigare bekräftade bronsåldersdateringar av tre fornborgar i Uppland som referens för Västmanlands fornborgar och överblickar andra närliggande fornborgar. Både Näsborgen och Kastena Skans konstateras vara konstruerade under bronsåldern. / There are two main areas of rock art in Västmanland county with a close relation to the ancient shorelines. In both areas, there are hillforts that have not yet been dated. The aim is to date Näsborgen and Kastena Skans in eastern and western Västmanland by using the geographic information system QGIS and ancient shoreline data obtained from Geological Survey of Sweden (SGU). Additionally, the hillforts are considered from a landscape perspective and their relation to rock art sites and heaps of fire-cracked stones, which support Bronze Age datings for these hillforts. The analysis uses previously confirmed Bronze Age datings of three hillforts in Uppland as a reference for the hillforts in Västmanland and provides an overview of other nearby hillforts. Both Näsborgen and Kastena Skans are determined to have been constructed during the Bronze Age.
