Nojpetén (also known as
Tayasal) was the capital city of the
Itza Maya kingdom, located on an island in
Lake Petén Itzá in the modern department of
Petén in northern
Guatemala. The island is now occupied by the modern town of
Flores, the capital of the Petén department. Nojpetén had defensive walls built upon the low ground of the island; they may have been hastily constructed by the Itza at a time when they felt threatened either by the encroaching Spanish or by other Maya groups.
