(JTA) — The oldest synagogue in Buffalo was demolished despite the efforts of two demonstrators, who chained themselves to a pillar in the building.

The Jefferson Avenue shul was demolished on Saturday after the demonstrators, identified as David Torke said he and Rabbi Drorah Setel, were peacefully removed from the building and detained by police, the Buffalo News reported.

The building posed a safety hazard, according to police, and was condemned. Preservationists said the building should have been listed as a historical landmark.

The building was designed in 1903 by A.E. Mink and was home to Congregation Ahavath Sholem, also known as Jefferson Avenue Shul, according to the Buffalo News. The building was sold in 1960 to Saints Home Church of God and later to Greater New Hope Church of God in Christ, which owned the building for about 30 years. The building has been empty since 2005.

The demolition crew at first did not realize that there were people in the building. Eight other demonstrators remained outside of the building.
