about fifty examples that have been discovered in Scotland. It was
thought that these forts were peculiar to Scotland. However, they are
also found in County Londonderry and County Cavan, in Ireland. On
mainland Europe, they have been identified in Upper Lusatia, Bohemia,
Silesia, Saxony and Thuringia. A further example can be found in the
Ucker Lake, in Brandenburg, where the walls are formed of burnt and
smelted bricks. There are also displays in several places in France,
such as Châteauvieux, Péran, La Courbe, Sainte Suzanne,
Puy de Gaudy and Thauron
some forts that have been placed on practically infusible rock. The
quartz conglomerates of the Old Red Sandstone at Craig Phadraic and
on the limestone of Dun Mac Uisneachain are good cases. Here pieces

considerable distance. This demonstrates that the act of
vitrification was deliberate.
many more examples from Malta, Egypt, Iraq, Sudan, South East Asia
and others that are speculated to fall into the grouping. However,
these have not all been subjected to scientific testing like the
European cases. They simply appear to be glazed finishes on equally
large objects or on walls that are impossible to fire conventionally.
In many cases, it looks as if there has been the deliberate action of
a great heat.

It mostly revolves around whether the stones are vitrified or not. In
these cases, vitrification appears to be present on different kind of
stones, and seems to have been caused by deliberate action. This
article will now concentrate on these Peruvian cases where there are
indications of heat treatment.
