In 1947 a chamber tomb of the Hellenistic period built throughout with white and blue marble, quarried from the mountain above Mylasa, was discovered within the modern town of Milâs. It consists of two chambers, each measuring internally 2.05 x 3.20 x 2.91 m. The walls are 0.90 m. wide and are composed of two rows of blocks, worked only on the outer surface and filled in compactly with smaller pieces of marble. Each block is attached to the next by means of clamps. The floor today is at a depth of 4.50 m. On either side of each, and occupying its whole length, is a bed formed by a horizontal slab let into the wall, with a vertical slab resting on its outer edge. On the left side, the spaces beneath the beds, where interments were also found, were closed by long thin blocks.
