During the Neolithic era—the last stage of the Stone Age—inhabitants of the Mediterranean island of Malta erected grand religious structures that the World Heritage Sites committee calls “unique architectural masterpieces.” This Friday, art historian Dr. Allan Langdale will give a talk on the island’s three main temples: Ħaġar Qim, Mnajdra, and Tarxien. The temples, built in phases between 3,500-2,500 BCE, are the oldest free-standing structures on Earth, according to Wikipedia. The event takes place Friday, July 22, at 7 p.m., Architectural Foundation of Santa Barbara, 229 East Victoria St. (entrance on Garden St.). There is a suggested donation of $10 at the door.
