Tour Stops & Points of Interest (6)

1

Museum of the Order of St John

Start exploring at St John's Gate, a magnificent 16th-century structure that served as the entrance to the Priory of the Knights of St John. This site dates back to the 1140s when the Order was established to provide medical care for pilgrims in Jerusalem. As you look at the stone gatehouse, imagine the knights in their black robes with white crosses. Over the centuries, this building has worn many hats, from a printing house where Samuel Johnson worked to a tavern run by the father of the man who founded the modern St John Ambulance. It is a rare surviving piece of medieval London that sets the stage for the layers of history you will uncover today.

2

Clerkenwell Green

A short walk brings you to Clerkenwell Green. Despite the name, it hasn't been a grassy green for centuries. This space has been a hotbed of radicalism and protest since the 14th century. It was here that the Peasants' Revolt gathered and where Victorian reformers held massive rallies. Look for the Marx Memorial Library, located in a building where Vladimir Lenin once edited the newspaper 'Iskra' (The Spark) while in exile. The architecture surrounding the square, from the imposing Old Sessions House to the modest workshops, reflects Clerkenwell's past as a center for clockmaking, gin distilling, and political upheaval.

3

Postman's Park

Tucked away near the old General Post Office, Postman's Park is one of the City's most poignant hidden gems. Its name comes from the postal workers who used to eat their lunch here. The park's centerpiece is the Watts Memorial to Heroic Self-Sacrifice, a long wooden cloister containing glazed Doulton tablets. Each tablet tells the story of an ordinary person who died while trying to save the lives of others. These brief, tragic accounts offer a window into the dangers of Victorian life and the enduring spirit of human bravery. It is a quiet, reflective space that provides a stark contrast to the bustling city streets just outside its walls.

4

St Giles-without-Cripplegate

As you enter the Barbican Estate, you will find the Church of St Giles-without-Cripplegate. The term 'without' means it stood outside the city walls, near the old 'Cripplegate' entrance. This church is a survivor; it has been rebuilt several times due to fires and Blitz damage. It serves as a fascinating anchor between the old world and the new, with its medieval stone walls surrounded by the towering concrete pillars of the Barbican. Notable figures like the poet John Milton are buried here, and Oliver Cromwell was married at its altar. It remains a spiritual heart for the modern residents living in the surrounding high-rise towers.

5

Barbican Conservatory

Hidden within the concrete layers of the Barbican is a tropical paradise. The Barbican Conservatory is the second largest in London, housing over 2,000 species of tropical plants and trees. Here, the 'Blooms' of our route truly take center stage. The sight of lush green vines draping over Brutalist concrete beams creates a surreal, 'post-apocalyptic chic' aesthetic that is a favorite for photographers. It is a testament to the architects' vision that nature could be integrated directly into a high-density urban environment. Note that while entry is free, it usually requires a pre-booked time slot, so it is always wise to check availability in advance.

6

The Barbican Centre

Your self-guided adventure concludes at the Barbican Centre, the heart of this world-renowned Brutalist estate. Completed in the 1980s, the Barbican was designed to be a 'city within a city,' featuring elevated walkways, lakes, and residential towers named after famous historical figures. The textured 'pick-hammered' concrete was finished by hand to give it a rugged, stone-like appearance. As you wander through the foyers or sit by the lakeside terrace, you can appreciate the utopian ambition of the project. It remains one of the most significant examples of Brutalist architecture in the world, serving as a vibrant hub for music, theater, and art.
