King Ashur-bel-kala of the Middle Assyrian Empire created zoological and botanical gardens in the 11th century BCE. In the 2nd century BCE, the Chinese Empress Tanki had a “house of deer” built, and King Wen of Zhou kept a 1,500-acre (6.1 km2) zoo called Ling-Yu, or the Garden of Intelligence. Other well-known collectors of animals included King Solomon of the Kingdom of Israel and Judah, Queen Semiramis and King Ashurbanipal of Assyria, and King Nebuchadnezzar of Babylonia.
