Zion Chapel on the site of the old malthouse, at the junction of Last Lane and Queen Street, then came into existence. Apparently the small congregation of Presbyterians that had gathered around Mr. Davis had occupied the old malthouse on suffrance, and in the year 1703, the year following the death of Mr. Thomas Papillon MP, his son Philip, who was a candidate for the representation of Dover, purchased and leased the old malthouse to the Presbyterians who transformed it, without much structural alteration, into a chapel.
Theres is also mention of one somewhere in the Western Docks - not sure if this is the same as the Pentside Chapel ?
