[1] Antioch Hall (known to Antiochians as Main Building) was constructed in the 1852–53 timeframe by architect Alpheus Marshall Merrifield.

[4] This included the inset of a concrete structure inside the original building which stabilized it and insulated its interior against weather and degradation.

[4] Some restoration has been done, the largest from a $500,000 directed grant from Yellow Springs Community Foundation in 2019, intended to tackle projects of immediate need such as reintroducing heating.

[6] In 1953 it was extensively reconstructed following a significant fire in February of that year, with use of an interior steel framework supporting four-inch reinforced concrete floors which made the building more fireproof.

[10] Renovated in 1994, it too was damaged after closure in 2008 when a sprinkler system pipe on the fourth floor of the unheated building burst in December of that year, flooding the structure’s east end.
