Two possible churches, both now in secular use. Can you confirm the status of either?

The first is now used by the Liskeard Silver Band. SX 251 643. © Andrew Ross. Janet Gimber has advised that this was a Bible Christian Chapel, built in 1854 or 1858 depending on which source is consulted, and extended in 1881. Date of closure not currently known.

The second has a carved symbol above the door - Jewish? Masonic? SX 251 646. © Andrew Ross. Janet Gimber has advised that this was/is Masonic.
