To which city did the Assyrian commanders take King Manasseh as a captive?

Answer: Babylon

Because Manasseh ignored the LORD, the commanders of the king of Assyria captured him, bound him and took him to Babylon.

“And the LORD spoke to Manasseh and his people, but they did not listen. So the LORD brought against them the military commanders of the king of Assyria, who captured Manasseh, put a hook in his nose, bound him with bronze shackles, and took him to Babylon.”— 2 Chronicles 33:10-11 (BSB)
