Question: What city in Texas is home to the country’s largest rooftop park?

Answer: Houston. The five-acre Skylawn sits atop the former Barbara Jordan Post Office, which was decommissioned in 2015. A developer turned the 555,000-square-foot building into an entertainment and cultural center called POST Houston, which opened in 2021.

The venue is also home to the one-acre Skyfarm, among the 10 largest rooftop farms in the world. In the heat of summer, rooftop temperatures are up to four degrees cooler than nearby buildings without greenery.
