How to Use This Groton, Connecticut Map

This interactive map shows the street layout and satellite imagery for Groton, Connecticut. 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. Drag the map to pan to any area of Connecticut or beyond.

Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, 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).

TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Groton.

Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference 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 a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams 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 cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Groton holds a quiet command over the landscape, where the Thames River carves a path toward the distant salt air. It lies 1.2 miles east-southeast of New London, CT (from New London, CT: bearing 109°T), and is situated 2.5 miles south-southwest of Conning Towers Nautilus Park. The land rises sharply to meet the sky at Fort Griswold Hill, a granite prominence that anchors the local topography. Beyond the river, the terrain softens toward the water, where the silhouette of Powder Island breaks the surface of the tide. Gentle depressions like Sanctuary Basin hold the memory of ancient glacial retreats, while the sheltered waters of Hay Harbor rest seven miles to the south. Visitors often remark on the light at dusk, which turns the gray water into a sheet of hammered silver before the evening chill settles over the ground.

Groton maintains a legacy defined by the weight of iron and the precision of maritime engineering. The economy has long been tethered to the pulse of the shipyards, where the roar of industry once echoed daily against the riverbanks. Workers here have spent generations crafting vessels that navigate the deep, a tradition that lends a serious, industrious character to the local streets. This mechanical heritage is balanced by the persistence of small-scale commerce that remains grounded in the realities of a working waterfront. The rhythm of the workweek dictates the town’s pace, creating a steady, predictable hum that persists long after the sun dips below the horizon.

Cultural life in Groton centers on a deep reverence for the past, preserved with care at the Fort Griswold Battlefield Area. This site serves as a somber reminder of the sacrifices made in the pursuit of independence, standing as a landmark for both residents and those passing through the region. Among the figures who have shaped the broader awareness of the area, the diplomat Silas Deane remains a recognized name associated with the early struggles of the nation. The atmosphere remains one of modest, dignified resilience, punctuated by the occasional sound of a bell ringing from the harbor. Life here moves with a deliberate purpose, reflecting a community that values its place in history as much as its role in the modern world.
