The Google maps easter egg is on Earl’s Court Rd in London, England. If you look at the directions, you will see a double arrow pointing to the police box sitting next to the kiosk. When you select that arrow, you enter in the TARDIS to explore.
The TARDIS is an iconic ship on the popular TV show Dr. Who. TARDIS stands for “Time and Relative Dimension in Space”. The story of the TARDIS is has a chameleon-cloaking device that can blend in with the environment, but this feature is broken and can only project a police box. The TARDIS also is bigger on the inside than the out.
Unfortunately, we can only explore the main room of the TARDIS. You can move around that main room – climb the stairs and see the console from multiple angles. You can also belly up to the main navigation console and get a first-hand look at the gadgets and gizmos of the TARDIS.
When done, make sure the door is closed and head back down Earl’s Court Rd.
