Propose marriage at the Peter Harrison Planetarium or Meridian Line

If the stars have aligned and you found the person you want to spend the rest of your life with, it might be time to pop the question. As proven by Ross and Rachel in Friends, planetariums are pretty darn romantic, so head to the Royal Observatory for your big moment. After you’ve done a bit of stargazing, get down on one knee.


The plan

  • With an entire 132-seat venue to yourselves one of our astronomers will be on hand to make sure everything runs smoothly.
  • You will be given tickets to make it look as if you have VIP access, concealing your true plan for as long as possible.
  • Our astronomer will begin a normal planetarium show, before handing the show over to you.
  • A range of spectacular astronomical sights can be displayed on the dome, including the constellations, a fly-out from the Milky Way, or a journey through Saturn’s rings.

Our proposal package includes:

  • Exclusive use of the Planetarium with one of our astronomers.
  • VIP Planetarium E-ticket – to maintain the cover story.
  • Complimentary visit to the Prime Meridian of the World with spectacular views over central London for your photograph.
  • Glass of bubbly to celebrate
Cost: £500
