London's Postal Museum has just reopened after a 17-month overhaul.
If you have any interest in postal history, you must visit.
A 10-minute trip on the Mail Rail is the star attraction
See the telegrams Titanic sent as she sank, a 19th century mail coach and the guns carried by 19th century postmen.
You can also view vintage Post Office posters and gaze at different stamp designs – some that came to fruition, and some that didn't. You can even see the original sculpture of the Queen used on the nation's stamps.
And then there's the star attraction. An opportunity to ride on a section of the "Mail Rail" – part of the six-mile subterranean track that took post from Whitechapel to Paddington, connecting with train stations and sorting offices along the route.
In its heyday, the mail train operated for 22 hours a day and employed more than 200 staff.
Closed in 2003 after a 75 year run, from September visitors will be able to experience a 10-minute sample of London's other underground railway.
Have small ones in tow? The Sorted! play area offers under 8s the chance to sort the mail, try on uniforms and get the parcels delivered on time.
And this August there will be plenty of art activities and storytelling.
“We are absolutely delighted to welcome our first visitors to The Postal Museum. We’re anticipating an extremely busy first month, with lots of fun activities planned for families," Adrian Steel, the museum's director, told the Register.
"Then, on Monday 4 September, Mail Rail trains will depart for the first time – a truly historic moment for London."
