California Is Home To 13 Palaces So Beautiful They Feel Almost Unreal
Palaces rarely feel like something you stumble upon by accident. Towering walls, grand staircases, and arched windows usually belong to faraway places shaped by centuries of royalty and tradition.

The result is a collection of palatial estates that feel transported from another world, yet grounded firmly in California landscapes.
Some overlook the coastline, where sunlight reflects off stone and glass with dramatic effect. Others sit quietly among trees or above small towns, adding elegance to places known for simplicity.
