Mexican Billionaire Carlos Slim’s 20,000 square feet New York City townhouse is on sale and you can now take a look inside.

Carlos Slim Helu is the second richest man in the world and the first richest person in Mexico with a fortune of $61.4 billion.

His magnificent fifth avenue town house was put on the market in May. At $80 million, it is the fifth most expensive property for sale in New York, according to real estate website Curbed.

When the property was listed, no interior photo of the Upper East side residence were available and the curious could only peak at its Beaux Art façade.

But listing agency Sotheby’s, which is handling the sale, recently posted pictures of the early 20^th Century mansion.

The building rises over five floors and 25 rooms, including eight bedrooms, 10 full bathrooms and beautiful terrace overlooking the Metropolitan Museum of Art.

The interiors feature soaring ceilings, hand-carved wood panelling, trompe l'oeil accents, gold-leaf trimmed fixtures, and intricate plaster friezes as well as a stunning staircase connecting the five floors, according to Sotheby’s.

The house was originally built in 1901 and is officially named the Benjamin N. and Sarah Duke House
