Carolands, Beaux-Arts mansion in Hillsborough, California.
The Carolands estate encompasses 98 rooms across five acres of land, featuring classical French architecture with symmetrical proportions and decorative elements throughout the structure.
Built in 1916 for Harriett Pullman Carolan, daughter of the Pullman Company founder, the mansion represents the architectural preferences of wealthy Americans during the early 20th century.
The property incorporates French design principles through collaboration between Parisian architect Ernest Sanson and American architect Willis Polk, who managed the construction process.
The estate maintains limited visiting hours, requiring advance reservations for guided tours that showcase the mansion's architectural features and historical significance.
Located at the highest geographical point in the area, the mansion provides views of San Francisco Bay through carefully planned gardens designed by French landscape architect Achille Duchêne.
