AIA Orange County Society offers monthly lectures from renowned professional archaeologists who share insights into Old and New World civilizations with the latest cutting-edge research. Our lecturers’ topics span the globe and occasionally venture into space. Each year AIA national provides our society with two lecturers. All other lectures are supported from donations by generous sponsors. The cost to sponsors a lecture is $300, and both members and non-members have done this. Mostly it’s the satisfaction of helping that generates a donation, but it is tax-deductible to the extent allowed by law.
