Join art patron Steven Oliver for a privately led 2-3 hour walking tour of his site-specific collection. The 100 acre Alexander Valley Oliver Ranch is home to commissioned installations by artists such as Richard Serra, Bruce Nauman, Andy Goldsworthy, Ursula Von Rydingsvard, Ann Hamilton and Martin Puyear.

This amazing collection of modern art installations is not normally open to the public and has been made available to the Urban Auction this year.
