Perch Rock Lighthouse, New Brighton Wallasey.

The first lantern was erected on the site in 1683 as a crude wooden tripod but as the Port of Liverpool developed it was deemed inadequate as it required constant maintenance and only produced a limited light.
The current lighthouse was constructed in 1827 out of blocks of interlocking Anglesey granite and it is 29 m (95 ft) tall.
It was first lit in 1830 and displayed two white flashes followed by a red flash every minute. The light source was thirty Argand lamps, mounted on a three-sided revolving array (ten lamps on each side, with red glass mounted in front of one side).
There were also three bells mounted under the gallery to serve as a fog signal. They were tolled by the same clockwork mechanism that caused the lamps to revolve.
The lighthouse was in continuous use until decommissioned in October 1973 having been superseded by modern navigational technology.
