How to Use This Monrovia, Maryland Map

This interactive map shows the street layout and satellite imagery for Monrovia, Maryland. 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 Maryland 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 Monrovia.

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.

About Monrovia, Maryland

Monrovia is a locality in Frederick County, Maryland, United States. It has a population of approximately 2,702. The population density is 464.7 people per km². Monrovia is located at 39.3595°N, 77.2749°W. It observes the Eastern Time (America/New_York) timezone. ZIP code: 21770.

Monrovia occupies a quiet stretch of land where the landscape transitions into the gentle, persistent slope of the Piedmont. It lies 4.5 miles north-northeast of Green Valley, MD (from Green Valley, MD: bearing 17°T), and is situated 8.0 miles east-southeast of Frederick. Bush Creek carves a narrow path through the earth here, its waters moving with a steady, unadorned purpose as they navigate the soil and stone. To the west, the Blue Ridge Mountains rise against the horizon, a hazy, permanent serration that defines the limit of the view. The air carries the scent of damp earth and late-season grasses, and the light at dusk settles over the fields in long, thin bars of amber that sharpen the edges of the trees. A short distance away, the quiet basin of Lake Anita Louise holds the reflection of the sky, offering a stillness that mirrors the measured pace of the land itself.

Monrovia retains a character shaped by the steady labor of the soil and the slow expansion of the regional corridor. The local economy finds its roots in the agrarian traditions that once dominated this territory, though the modern rhythm now balances between those historical echoes and the movement of people commuting toward busier centers. Residents often gather at New Market Park, a modest space that provides a communal anchor amidst the surrounding pastures and development. The history of the area is written in the preservation of its rural boundaries and the way the infrastructure follows the natural contours of the terrain. Life in Monrovia remains defined by the changing seasons, marked by the transformation of the landscape from the pale greens of early spring to the muted, weathered browns of the dormant winter months.

About This Monrovia Map Page

This page provides an embedded street and satellite map of Monrovia, Maryland. Coordinates: 39.359462, -77.274891. Live weather conditions are sourced directly from the National Weather Service. Real-time local and world news feeds keep the page current.

Detailed location data for Monrovia includes the ZIP code (21770), telephone area code (410, 443), county seat of Frederick County (Frederick), and school district assignment (Frederick County Public Schools).

Search Maps opens a second, independent map. It searches OpenStreetMap for any US town, county or landmark by name; offers USGS topographic maps and USGS aerial imagery as base layers; overlays a labelled U.S. National Grid (USNG) so the map can be read like a printed topographic quad; measures distance and grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a USNG grid reference and as latitude and longitude. Map tiles require cell coverage, but a GPS position does not, so the coordinates remain correct even where the map cannot load.

Location data is drawn from the USGS Geographic Names Information System (GNIS) and cross-verified against 2020 US Census records by coordinate proximity. Population figures are sourced from the 2020 US Census.
