The Mail Rail

The original underground postal railway, now one of London's most atmospheric event spaces.

Underground. Industrial. Unforgettable.

The Postal Museum in Clerkenwell tells the story of the Royal Mail and Britain's extraordinary postal history. Beneath it runs Mail Rail, a narrow-gauge underground railway that once carried millions of letters across London. It is one of the most singular and atmospheric event spaces in the city, and one that guests talk about long after any event held within it.

As an accredited production partner, Kudos AV has worked within both of the museum's principal event spaces. The Mail Rail venue is a genuinely industrial blank canvas, with vaulted brick ceilings, exposed ironwork and a raw architectural character that requires thoughtful production to bring the best out of it. It is available for exclusive hire from 5pm on selected dates throughout the year, once the museum has closed to the public.

The museum's award winning reputation for events has been built on the back of its unique environment. Product launches, gala dinners, networking events, corporate receptions and awards ceremonies all benefit from the sense of occasion and discovery that the Mail Rail creates. Guests who have never encountered this space arrive expecting a museum and leave having experienced something genuinely different.

The spaces.

The Mail Rail venue itself accommodates up to 275 guests for a standing reception and 150 for a seated dinner. The exposed brickwork, vaulted ceilings and the tunnel structure itself provide a backdrop that no amount of set dressing could replicate. The space has a genuine sense of place and history that elevates every event held within it.

The Courtyard at street level provides a lighter, more contemporary alternative or addition to the underground spaces. It accommodates up to 120 standing or 60 seated, and is well suited to receptions, networking events and pre-dinner drinks. The combination of Courtyard and Mail Rail allows for a flowing evening experience that moves between entirely different environments.

The venue is located on Phoenix Place, WC1X, within easy reach of Farringdon, King's Cross and Chancery Lane stations. Hire is available from 5pm daily and the venue can be taken exclusively, allowing full creative control over the experience.

Kudos AV at The Postal Museum.

The Mail Rail's industrial character creates specific acoustic and technical challenges. Low brick ceilings and hard reflective surfaces require careful speaker selection and placement. Lighting in an underground environment with no natural light demands a full creative approach from the outset. Our team plans every installation in consultation with the museum's events team, ensuring safe, effective and visually compelling production throughout both spaces.
