This year is a landmark year for the RHS Chelsea Flower Show. Not only is it celebrating its centenary year, but the 100-year ban on garden gnomes has also been lifted! Gnomes were by no means the most unusual garden feature at this year’s show, however, as innovative sculpture,  unusual materials and unique aesthetics have been used to create some truly memorable displays.

Other gardens have a more sombre mood, however, with many raising awareness for charities such as Arthritis Research UK and Sentebale. Throughout the show the gardeners’ incredible skill and dedication is abundantly clear, and will no doubt inspire visitors to make the most of their own green spaces at home.

Visitors who walk down Sloane Street on their way to the show this year will also notice two floral elephants on its east side, which were installed on Monday to raise awareness of Habitat for Humanity’s Animal Ark initiative. This charity project, alongside many others, will have its own garden at the 2014 show.

As for so many great London institutions, the first 100 years really are only just the beginning!

The Mousetrap: 61 years
The Mousetrap is the world’s longest-running play, captivating London audiences since 1952. Packed with suspense, the classic whodunit takes place in a remote English country house hotel during a snow storm.

Les Miserables: 28 years
Now in its 28th year, Les Misérables is the longest running musical in the world.  This global stage sensation has been seen by more than 60 million people in 42 countries.

The Phantom of the Opera: 27 years
The Phantom of the Opera has reigned at Her Majesty’s Theatre for a whopping 27 years. Andrew Lloyd Webber’s epic musical, which opened on 9 October 1986,  tells the tale of a disfigured composer who terrorises the Paris Opera in an attempt to make his protégé a leading lady.

The Woman in Black: 24 years
The Woman in Black has been terrifying audiences since 1989, making it the second longest-running play in the history of the West End.

The Lion King: 14 years
Still a roaring success, The Lion King is celebrating its 14th year at London’s Lyceum Theatre.

The Lion King is one of five musicals to play for 10 or more years on both Broadway and the West End.

Mega-musical We Will Rock You has been a permanent fixture at the Dominion Theatre since 2002. Based on the songs of rock legends Queen, the show is set in a futuristic world where rock music has been banned.

Stomp: 10 years
Celebrating its 10th year in London, Stomp has been kept fresh with new routines, choreography and music. As its title suggests, talented performers use everything from zippo lighters to bin lids to hammer out a feel-good rhythm.

Billy Elliot: 8 years
Billy Elliot has been dazzling London’s West End since 2005 with its heart-warming tale of a young boy who struggles against the odds to fulfil his dream of becoming a ballet dancer. The all-singing all-dancing musical features an acclaimed score by Elton John.

Wicked The Musical: 7 years
Wicked The Musical made its West End debut seven years ago in 2006. Still going strong, the show welcomed its five millionth audience member last month. The award-winning musical tells the story of an unlikely but profound friendship between two young trainee witches who meet at sorcery school.

Written by Tom Wareham, Curator of Maritime and Community History at the Museum of London Docklands.

Today the Museum of London Docklands celebrates its 10th anniversary as a museum – though the building itself is 210 years old and a grand and rare survivor of London’s commercial Georgian past.

Every morning as I arrive at work I am still impressed by the monumental scale of the warehouses built by London’s sugar merchants and plantation owners – even if only two of the buildings survived the firestorm of the Blitz in 1940.

On a warm day, as you cross the dock basin from the modern cityscape of Canary Wharf, the plum-coloured brickwork of the warehouses glows in greeting but, 20 years ago things were very different.  Broken windows, shattered doors and frames, leaking roofs, debris and rubbish cluttered the buildings.  It took millions of pounds to restore the building – and it took years of work to convert it into the exciting modern museum that now attracts thousands of visitors from all over the world.

The museum certainly has a unique effect on visitors who, as they discover the modern galleries, are slowly absorbed and captivated by the soft brickwork and original honey coloured timbers of the building itself. It’s as though the building itself breathes the history of the port that is being narrated in the galleries. No wonder visitors are so surprised and delighted when they come here. So, happy birthday Museum of London Docklands!

A guest post by the Museum of London as part of our Visiting the Past series. Look out for more London history next week.

Mike Clewley, Cultural Tourism Officer at the Greater London Authority (GLA) introduces his pick of immersive performances in London:

As Shakespeare once wrote, “All the world’s a stage” so why should we confine theatre to traditional venues? London is home to a variety of incredible immersive experiences to enjoy whether you’re looking to dine out or just watch a film.

You may already be aware of this summer’s exciting new production from Punchdrunk and the National Theatre but if you’re the type of person who likes surprises and wants to be part of the experience, as well as being able to tell your friends “you’ll never guess what I did in London!”, then read on.

Secret Cinema

This is the closest you can get to immersing yourself in the fantasy world portrayed within a film without actually being on the screen. Hot off the heels of past successes including the Shawshank Redemption, Lawrence of Arabia and Bugsy Malone (including a massive custard pie fight), Secret Cinema continues to take London theatre, and its audience, to strange, new places.

Holding true to their mantra of “Tell No One”, you won’t know what you’re in for until you’re there, but this summer’s event promises to be intriguingly G.O.O.D.

The Ginger Line

There are some great pop-up restaurants in London but The Ginger Line also serves up artists, chefs and actors for one of London’s most unique dining experiences. Adventurous diners make their way to a secret location (always on the East London Overground line, which is ginger coloured, hence the name) and are treated to a mix of theatre, cabaret and cocktails to meet new friends over fantastic food and new surroundings. Look out for the next The Ginger Line event this summer.

Mike Clewley is Cultural Tourism Officer for the Mayor of London: “I’m in a very privileged position to represent the kaleidoscope of culture on offer in this great city. I’m passionate about history, art, music, film and discovering those moments in life that will make you go “wow!”. I love the fact that London is so difficult to sum up and why it’s so great but that’s what makes it the best city on the planet”.
