2 Kings 25:13, 17

Now the Chaldeans (Babylonians) smashed the bronze pillars which were in the house of the LORD and their bases and the bronze sea (large basin) which were in the house of the LORD, and carried the bronze to Babylon.

The height of the one pillar was eighteen cubits (27 ft.), and a capital of bronze was on top of it. The height of the capital was three cubits (4.5 ft.); a network (lattice work) and pomegranates around the capital were all of bronze. And the second pillar had the same as these, with a network.
