The I.O.O.F. Hall
The I.O.O.F. Hall was built in 1852 on a foundation of brick with
corners of dressed rhyolite tuff. Diamond Springs Lodge No. 9 was the
first lodge instituted in El Dorado county, and one of the first in the
state. The Odd Fellows still use their “fine commodious hall in the
two-story frame building on the hill, visible far away.” It remains in
excellent condition and looks much as it did when it was first
constructed, if you ignore the air conditioner.
