With over eight-hundred episodes and nearly three-hundred adventures on TV, the Doctor has visited countless strange worlds and unusual time periods... but not all of them have we actually seen on-screen.
Referenced in passing, left to the imagination or entirely off-limits, we've never seen these notable locales in the Doctor Who Universe explored by the Time Lord on our TV screens.
From the home planets of several iconic alien menaces to key locations in the programme the Doctor has never actually stepped foot in - these are the most intriguing and most surprising places we've never seen.
This list will be focusing on the Doctor Who TV series only, so you might find that planets, time periods, and locations travelled to in comics, books, or Big Finish Audio dramas appear on this list. These interesting locations, however, should be seen on our screens - with some even helping to fill in important gaps in the Doctor's timeline.
Some of these entries are surprising, and some of them have been discussed at length, but all of them are important to Doctor Who's history.
Read on to discover the top picks for Places The Doctor Has Never Visited On-Screen...
