The Golden Triangle refers roughly to homes in the mid-country section of the city of Greenwich, Conn., which encompasses nearly two-thirds of the town's geography.
One- and two-acre lots are most common. The remarkable amount of open space compared to the rest of Greenwich comes from preservation efforts led by the Greenwich Land Trust and other conservation organizations.
In addition to palatial estates, the area is known for various waterways, winding country roads, forests, meadows and gorges carved by past glaciers.
The Golden Triangle is 87.3% white, 7.4% Asian, 2.5% Latino, 1.9% black
