It’s not every day you find three superbly appointed, fastidiously restored, Upper East Side limestone townhouses and one brownstone hoisted together onto the market. Then again, this is Manhattan. You can expect to see anything at least once.

Behold $155 million in total real estate listings at 12, 14, 16 East 62nd Street ($120M) and a separate parcel at 18 East 62nd Street ($35M) to one of the world’s richest banking families.

According to the New York Post, the townhouses are owned by the billionaire Safra family, headed by Lily Safra, widow of Edmond Safra, who was murdered in Monaco in 1999.

As the NYPost explains:

The Safra family originated in Aleppo, Syria, where they were traders before a circuitous route via Lebanon eventually landed them in Brazil. The eldest Safra, Joseph, is reportedly the world’s richest banker. The family’s billions include a large stake in the General Motors Building.

The townhouses, at 12, 14 and 16 E. 62nd Street, between Fifth and Madison Avenues, were built as separate homes with windows and doors lining up. They currently house wealthy tenants.

However, the properties would make an impressive single family mansion if combined — with more than 70 feet of frontage on E. 62nd Street. At least one of the homes was formerly owned by the Astor family, according to one of the listings.

The listing is held by Sabrina Saltiel and Raphael De Niro of Douglas Elliman, who describe the grouping of three townhouses at 12-16 East 62nd Street as potentially suited for the creation of “a palatial single family mansion, club, embassy, or retail space.”

The units are all six stories tall and represent 73 feet of frontage on one of the most coveted blocks in one of the most  Old World moneyed streets in the city. Combined, the three townhouses offer 30,000 square feet of interior space.

Originally designed as a row of eight townhomes in 1879 by Breen & Nason, Architects, the three townhouses have gone through two total redesigns over the decades. In 1916, they were “reimagined” in 1916 in a neo-French classic style. In 2011, they were restored by Joseph Pell Lombardi Architects in 2011.

Each house features classic limestone facades, deep inset windows with Juliet balconies overlooking the tree-lined block, and a striking shared cornice. Inside, a breathtaking array of historic and thoughtful details abound, including soaring ceilings, grand proportions, hand-carved wood paneling, 23 fireplaces (some with original mantels), grand sweeping staircases ascending up to five stories, elevator, and fifth-floor skylights at No. 12 and No. 14. Combined, there are 11 terraces.

The adjacent five-story brownstone townhouse at 18 East 62nd Street is 22.5 feet wide and totals 9,520 square feet and cannot be easily combined with the three units next to it. The Post wrote that there had been speculation that the Safra family may have intended to include these properties are part of a synagogue they founded on East 63rd Street, however, they are now currently configured as a 13 “triple-mint” luxury rental apartments ranging from full-floor to triplex residences.

As for what happened to Edmond Safra, the Post had details about that, too:

New York society was gripped by the murder of Edmond Safra in Monaco in 1999. The legendary banker died in a house fire that was deliberately set, allegedly by Safra’s bodyguard and nurse, a former Green Beret named Ted Mahler, who maintained his innocence. Safra’s widow, Lily Safra — a socialite who has outlived three husbands — owns homes around the world, including a co-op at 820 Fifth Avenue, at E. 63rd St.
