Milbank House

Between Russian-born billionaire Roman Abramovitch's three-townhouse Upper East Side combo, Sarah Jessica Parker's Village two-fer plans, and the many similar but less newsworthy grandiose schemes by modern-day moguls to collect and build dream castles, the mega-mansion may seem like a sign of 21st-century excess. But the practice has a long history, as evidenced by this 54.5-foot-wide Greenwich Village property at 11 West 10th Street that just hit the market for a trophy-level $50 million, which could set a townhouse record below 34th Street, according to the New York Times. Built by renowned architect Ernest Flagg in the early 1800s, the duo was combined in the early 1900s by investor Jeremiah Milbank, creating a 16,560-square-foot, L-shaped property surrounded by 5,690 square feet of private terrace. Today, it's been renovated from stem to stern and is ready to welcome a new decade's decadence.
