Security expert and Simplex scion Chris Watkins relisted his Italianate mansion in Palm Beach this summer.

The asking price for the house—which measures a walloping 28,399 square feet—is $110 million; it was priced at the same amount when it last listed in 2019.

The 2003-built house, named Pietra Mare, is designed around a courtyard, with an extensive network of colonnades linking the various indoor and outdoor living areas. Details of the interiors spaces include limestone walls, inlaid marble floors, ornate wrought iron balustrades, hand-painted tile, and coffered ceilings.

Amenities in the home include a library, a formal dining room with a carved limestone fireplace, and a master suite with a private living room, a pair of baths, and a terrace overlooking the ocean. The grounds extend to over two acres, with the semi-enclosed courtyard featuring a massive swimming pool as a centerpiece.

Watkins sold Simplex, a company founded by his grandfather, in 2000 for $1.2 billion after growing the company and branching out into security systems.
