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.

Heaps of fire-cracked stone is an archaeological site category frequently found in Sweden. The heaps were constructed by piling a massive amount of deposited fire-cracked stones and occasionally they contain artefacts, for example, grindstones, ceramics or bones from both humans and animals. The heaps are sometimes also constructed with complex inner stone patterns in forms of e.g. circles and spirals. The heaps have been found all over Sweden, but the largest concentration is associated with the county of Uppland, north of Stockholm in eastern Sweden. In general, the structures have been linked chronologically to the Bronze Age (1800 B.C.–500 B.C.), although the heaps might be one of the least understood features of Scandinavian prehistory, as a result of their complex and varying content and spatial location. The remains are thoroughly debated, and the interpretation of them varies, ranging from graves to household indications, from sacral to profane, from piles of waste to markers of claimed land. The interpretations of the fire cracked stone heaps have mainly been made by comparing the contents of the heaps with finds from the surrounding archaeological landscape.                  In this study, the heaps will be analysed by using a landscape perspective by which they will be examined in relation to dynamic high-resolution shoreline reconstructions, vegetation and local topography. By examining the heaps by applying a high-resolution landscape model, suggests that their placement patterns are strongly connected to past shorelines. The analysis has in turn resulted in a non-prejudicial dating method for the heaps. The shoreline model was in the next step tested by a comparison to 118 published 14C-dates associated with fire-cracked stone heaps by using Kernel Density Estimations (KDE). The main result of the study is that the high-resolution shoreline model, in combination with KDE, provides an effective dating method for heaps of fire-cracked stone, which in the extension suggests an alternative motive for the construction of the heaps.

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.
