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

The first, on Russell Street, 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.
