Zedekiah's Cave, also known as Solomon's Quarries, is a 5-acre (20,000 m2) underground meleke limestone quarry under the Muslim Quarter of the Old City of Jerusalem that runs the length of five city blocks. It was carved over a period of several thousand years and is a remnant of the largest quarry in Jerusalem.

Meleke, also transliterated melekeh or malaki, is a lithologic type of white, coarsely-crystalline, thickly bedded-limestone found in the Judaean Mountains in Israel. It has been used in the traditional architecture of Jerusalem since ancient times, especially in Herodian architecture. Though it is often popularly referred to as Jerusalem stone, that phrase can refer to a number of different types of stone found and used in or associated with Jerusalem.
