Secret Base is an extra large map added in the 10.4.0 update.
The map is situated near an ocean on the bottom of a mountain. The map contains a somewhat hidden base inside a rock formation, a dock area with a crane, and two guard towers, and a landing pad with a hovercraft. The base contains a storage room, an office, a room with 3 beds, a generator inside barrier fences, a desk with computers, and maps of the world on a screen.
The map was removed in the 11.0.0 update.
Both computers contain the "Blue Screen of Death", an infamous error screen on a Windows computer.
The room with the beds contain the sound of a heart beat monitor, which can also be heard in Hospital.
The map of the world contains blips on Eastern Australia, Argentina, China, Chad or Sudan, Eastern Russia (presumably Moscow), and Midwestern United States.
The blip on Russia maybe a reference to the location of the Pixel Gun Company; Rostov-on-Don, Moscow, Russia.
