The name of the city means u0022wallu0022 or u0022fortressu0022 in Mayathan. Probably the reason for this is that the whole city was surrounded by a six-meter-wide wall. The wall was only open to the sea. There were five entrances and two watchtowers. At that time, the city wall must have been practically unconquerable.u003cbru003eu003cbru003eBut earlier, around the 16th century, the city was also called u003cemu003eZamáu003c/emu003e. This name means u0022dawnu0022 in the Mayan language. No wonder – the sunrise over the sea looks quite spectacular from the ancient town.
