 Research has determined that the columns and gates date from around the mid-19th century, but were later added to (the addition of dog bars) to allow larger carriages and motorized traffic to enter the park.A report taken from the Pontypool Free Press in 1933 states that the gate's specifications were designed by T. E. Deakin in July 1835.Of particular interest are the vines on the pillars and bunches of grapes that would originally have been gilded, as were some acanthus leaves and finials on the gates.
