How much would you pay to visit some of London's biggest attractions? 

80p?, 9p? or even 1p? Well, that's exactly how much visitors paid over 50 years ago according to new research by Which?

Of course, the chances of paying that little nowadays are practically impossible, as the study has proved that the cost of tickets to the likes of London Zoo and Kew Gardens has risen astronomically.

If you visit the Tower of London today, you will be paying £34.80 per adult, but in 1974 that same ticket would've cost just 10p, 90p in today's money.

But that's not the only shocking discovery, as a ticket to see the waxworks at Madame Tussauds used to be 75p (£7 today) now you will be paying £33 advanced and a massive £42 on the day.

Elsewhere, a trip to London Zoo now costs £27 per person off-peak and at least £33 on the weekends.

Whereas in 1974, that ticket was 80p making it just £7.20 in today's money. 

A trip to the lovely Kew Gardens was just once 1p making that just 9p today, however, a ticket to the gardens will set you back between £12 to £24 in the current economy.

You might think the cost of a ticket has risen so much due to inflation, however Which? was able to dismiss that idea with their research as Rory Boland, editor of Which? Travel said: “Everybody should be able to afford a day out in the nation’s capital, but our research found people must dig ever deeper to afford entry to some of London's best-loved attractions.
