Building recording and assessment by PAYE Conservation on the Dietterlin-style entry gate pillars prior to their repositioning and restoration. The pillars are assessed as being of typical Jacobean style, although they are recorded in the listing as being 18th century in the Mannerist style. Previous 20th century repairs, using inappropriate materials, were found to have accelerated their deterioration. The gates and pillars are recorded as present in the 1680s (SyAC 50, 102). Wendel Dietterlin was a celebrated German architect who lived in the latter part of the16th century, whose particular style was much in vogue in Anne of Denmark’s time (he published many of his designs in the book Architettura, Nuremberg, 1598). Anne of Denmark rebuilt the house at Byfleet Manor in 1617; although subsequently rebuilt several times in later centuries the front courtyard wall with its pillars seems to have remained unaltered.
