It is a parcel comprised of 275 acres of the most sought after, naturally beautiful coastline that California has to offer. It sits in Marin county recognized by bizjournals.com as the 9th wealthiest county in the country. This parcel has been the subject of documentaries and it has been used as a prominent movie scene location for one of Humphrey Bogart’s alltime great films “Dark Passage.” Finally this location has housed some of this country’s most dangerous, notorious, and horrible criminals for the past 155 years. Marin County’s most valuable “undeveloped parcel” is none other than San Quentin Prison.
According to Forbes magazine, an old estimate from 2001, the San Quentin parcel of 275 acres situated on coastline is worth upwards of $665 million. This would make San Quentin the most expensive parcel in the country. If this land becomes available it would not be until, an estimated, 2011.
