Q: Question: How many seats did the addition in 1894-95 add? Passage:Christ Church was built between 1855 and 1857 to a design by the London architect Henry Martin. It was built as a chapel for Lancaster Grammar School and the local workhouse. The church was paid for and endowed by Samuel Gregson, a local industrialist and MP. In 1889 a south aisle was added, designed by the local architects Paley and Austin. It provided 152seats, and cost about 1,000. In 189495 a west baptistry was added by the same practice, then known as Paley, Austin and Paley. The same practice (by now Austin and Paley) converted the organ chamber into the Storey chapel, the organ having been moved into the south transept. In 1919 a war memorial was installed in the churchyard. It was in Derbyshire stone, high, and cost 400. This was designed by Henry Paley, then trading as Austin, Paley and Austin.
