About Royal Observatory

Ever wondered where time begins? Head to the Royal Observatory Greenwich to find out! This observatory is where the world's time zones are measured from – the Prime Meridian Line, 0° longitude, runs right through it! Perched on Greenwich Hill, you'll get amazing views of London, too. Set up by King Charles II in 1675, it's been a hub for all things astronomy, navigation, and time. You can check out telescopes, learn how sailors used the stars to find their way, and even stand with one foot in the East and one in the West!

Headout is really simple to use, in most cases you just have the QR code scanned as your ticket. It saves you a lot of money and gives you so many options. I would definitely recommend this to anyone going to London. You can check all the attractions included prior so you know it will suit you. Possibly the best way to see London!

Having the pass makes it much easier by avoiding ticket lines, however, there are some aspects that are good to point out: some facilities have rather limited opening hours, you have to take this into account when planning activities because you risk missing something: for example, we were not able to visit Westminster Abbey because a) on Sundays it is open only for worship, b) by postponing the visit to the following Tuesday morning we alas discovered that on October 1, that is when we wanted to go) the abbey opens at 1 p.m. Having to leave in the afternoon we missed it. Or the London Eye opens only late in the morning and, having to make reservations, the performance of the whole day suffers, because one cannot go to a museum, for example, as there is no time to do so either before (they open at 10 a.m.) or after (many close at 5 p.m. and between the time to go and the time to visit one would be squeezed in); moreover, the pass does not give priority of entry, despite the reservation. Finally, I would have preferred the pass to include more art venues than entertainment venues. Then if you are not able to use all the passes, the savings in spending are nullified
