Why it's Wildland
4.5A small, chapel-like brick building marks a once-important part of Greenwich’s water supply. Look closely at its outer walls for visitors’ initials and dates scratched into the brick, including marks from 1784, 1791, 1836 and 1920.
This is a compact historic discovery rather than a destination for a long outing: a rare, Grade II* conduit house with surviving Georgian and later graffiti, set within Greenwich Park. Its appeal lies in noticing a piece of hidden water infrastructure—and the personal traces left on its walls over centuries.

The experience
A brief heritage stop to see the conduit house from a permitted area and, if access allows, inspect the dated graffiti described by The Royal Parks. It can be paired with a wider Greenwich Park visit, but park facilities and routes are not detailed here.
Things to do
Look for the historic graffiti
The Royal Parks identifies marks on the back of the conduit house, including “R.E., 1784”, a possible “F. E.” dated 1791, the date 1836 and “Edward Ware, 1920”. Their authors are not known.
10–20 minutes
Notice the conduit house’s architecture
Look for the chapel-like form, brown brick and red-brick dressings. Historic England describes the building as a rare, particularly impressive conduit house, attributed to Nicholas Hawksmoor.

Verified history
The conduit house covers a reservoir and formed part of an early water-supply system for the Royal Hospital, now the Old Royal Naval College. Historic England dates it to the late 17th or early 18th century and attributes it to Nicholas Hawksmoor, who was Clerk of Works at Greenwich from 1698 to 1735. It is Grade II* listed and one of three related conduit houses associated with the earliest water supply for the Royal Hospital. The Royal Parks records graffiti on its outer walls from 1784, 1791, 1836 and 1920; the people who made the marks are unknown.
Hidden details
Four dates cut into the brick — The marks include 1784, 1791, 1836 and 1920. The Royal Parks offers possible identities for some makers but says they are unlikely to be known; treat those suggestions as speculation.
A rare piece of water-supply architecture — Historic England describes conduit houses as a rare building type and identifies this one as a particularly impressive example associated with the early water supply for the Royal Hospital.
