What Major City Was Originally Named Edo?
Did You Know!
Houston has an underground tunnel system larger than most people realize — and it connects 95 city blocks.
Beneath downtown Houston lies a 6-mile-long network of climate-controlled tunnels, originally built in the 1930s. What started as a single tunnel connecting two movie theaters has grown into an entire subterranean city — complete with restaurants, banks, salons, and access to major corporate buildings. Most locals know about it, but few realize just how vast and vital it is to the daily life of the downtown workforce — especially in the sweltering Texas heat.
