Discover a different **historical map** on your TRMNL every morning, drawn from the vast map collection of the **Library of Congress**. From 15th-century world maps and old sea charts to railway maps, military plans, city plans, and bird’s-eye views of growing American towns, each day brings a different glimpse into how people once mapped the world around them. Use it as a daily map discovery or a window into cartographic history. The collection contains more than 5,000 maps spanning centuries of history, with the oldest examples dating back to around 1450. Choose the types of maps and historical periods you want to explore, such as 18th-century city plans, 19th-century bird’s-eye views, or nautical charts. You can also leave the filters empty and let the collection surprise you. Each map includes its title, creator, and place of publication. One map stays on your TRMNL for the whole day, giving you plenty of time to explore the details before tomorrow brings a new one.
