Take a tour of San Francisco's 'Billionaires' Row,' where old money and tech execs collide

When the 1906 San Francisco earthquake and fire wiped the city clean, the wealthy stood around the burned rubble of their Nob Hill homes and took a cool, hard look at San Francisco Bay. The best view in the city was in Pacific Heights, and with that swath of real estate now up for grabs, the big money built there and settled in.

Through the Great Depression and both World Wars, the residents of Pacific Heights built mansions in an ex-frontier town that now has a median sale price of more than $1.12 million, according to Trulia.

Today's buyers have given this slice of San Francisco the name "Billionaire's Row." And those billionaires include a lot of tech names mingling with San Francisco's "Old Money" crowd - Oracle billionaire Larry Ellison, Apple design genius Jony Ive, and Yelp CEO Jeremy Stoppelman, just to name a few.
