Part of the structure, to the west of Wilson’s Arch and the Temple Mount, was discovered and documented by Charles Warren in the nineteenth century, followed by various archaeologists in the twentieth century.
Now that its excavation is complete, we know that it contained two identical magnificent chambers with an elaborate fountain between them.
The walls of the halls and the fountain were decorated with a sculpted cornice bearing pilasters (flat supporting pillars) topped with Corinthian capitals. The decorative style of the building is typical of opulent Second Temple-period architecture.
