Explore Sunken Marsh, Essex with this interactive street and satellite map. You can “grab” the Sunken Marsh map and move it around to re-centre it. You can change between standard map view and satellite map view by clicking the small square in the bottom left-hand corner of the map. You can use the zoom buttons on the lower right side of the map to zoom in or out to street-level detail.
This page also offers OS MAPS — Ordnance Survey Outdoor mapping and the OS Explorer 1:25 000 sheets — plus a labelled National Grid overlay, a distance and bearing tool, and a GPS grid reference readout. See How to Use This Map below. You will find live weather, local and world news further down the page.
This interactive map shows the street layout and satellite imagery for Sunken Marsh, Essex, England. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture to zoom in and out.
Click ⛶ Fullscreen to expand the map to fill your screen for a larger view. To return to the normal page view, press the Escape key on your keyboard, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).
Drag the map to pan to any area of Essex or beyond. Switch to Satellite view to see high-resolution aerial photography of Sunken Marsh and surrounding areas, including streets, buildings, parks and waterways.
OS MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row. OSM is the standard OpenStreetMap street map. Topo shows OS Outdoor mapping — contours, footpaths, bridleways and access land. Explorer 1:25k shows the OS Explorer sheets themselves: the orange-covered 1:25 000 maps walkers, fell runners and mountain rescue teams use, with field boundaries, rights of way and open access land. The search box finds any British town, village or landmark by name, so you are not limited to Sunken Marsh.
Reading the map like a paper Explorer sheet. Click Grid to overlay the OS National Grid, labelled along the edges exactly as a printed sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference such as NY 266 234 by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.
Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as an OS National Grid reference as well as plain latitude and longitude — the grid reference being what mountain rescue and the coastguard work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need mobile coverage, but a GPS reading does not — your grid reference stays correct even where the map itself cannot load, which in the Lakes, the Dales and the Highlands is often exactly where you need it.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

Sunken Marsh holds the weight of the Essex tide in its heavy, salt-crusted soil, a place where the suburban sprawl meets the relentless ache of the estuary. Grey light filters across the low-slung rooftops, illuminating a landscape defined by the quiet persistence of reeds and the distant, rhythmic hum of the Thames. Tewkes Creek snakes through the periphery like a bruised vein, carrying the silt of history toward the wider, grey expanse of the North Sea. Memories of a more martial past linger near the weathered remains of the Heavy Anti-Aircraft Gunsite, where the grass now softens the harsh edges of concrete bunkers meant for a war that has long since retreated into the archives. Residents walk their dogs toward the shimmering, brackish pull of Canvey Lake, their boots sinking slightly into the damp, unyielding earth. The economy here is a modest affair of commuters and ghosts, a quiet life lived in the shadow of the great, shifting marshlands that refuse to be fully tamed by brick or mortar. One might trace the melancholy lines of a Larkin poem in the way the wind whistles through the telegraph wires, undisturbed by the hurried pace of the modern world. Sunken Marsh remains a sanctuary of the overlooked, an enduring testament to the stubborn, brackish beauty of the East Anglian fringe.

Search Maps opens a second, independent map. It searches OpenStreetMap for any British town, village or landmark by name; offers OS Outdoor and the OS Explorer 1:25 000 sheets as base layers; overlays a labelled OS National Grid so the map can be read like a printed Explorer sheet; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as an OS National Grid reference and as latitude and longitude. Map tiles require mobile coverage, but a GPS position does not, so the grid reference remains correct even where the map cannot load.
