Smallest museum in the world. Free, open 24/7. Don't wear high heels if you want to go inside. Six men worked inside it breathing compressed air digging up the bottom of the river Liffey to create Dublin Port. Devised by engineer Bindon Blood Stoney in the 18th century it was in use until 1959. Totally cool.

I wouldn't go out of your way to see it, but if your near by its an interesting visit. Inside you can learn about its historical importance and how it was used to improve Dublin's port to allow for larger ships, which helped really put Dublin "on the map".

The Diving Bell, a massive 13 metre tall, 90 tonne feat of engineering, is located on the south side of the River Liffey and was used in the building of the Port’s quay walls from the Victorian era until the 1950s. It is now a museum.

Lovely walk along the Quays in Dublin.

An interesting slice of Dublin engineering prowess tucked away from the usual tourist attractions. The story of the diving bell is inside the bell. Well worth a visit.

Very nice beside Samuel Beckett Bridge , there is an Exhibition that show how there great diving bell was built its open to visitors

I must have passed this thing on Sir John Rogerson's Quay dozens of times on the way to and from work and - to my shame - never took a moment to wonder what it was (I was probably late for work 😏). It turns out there's a rather interesting story behind it. It is a huge diving bell that was devised to aid in the construction of Dublin Port quay walls. The construction techniques used were novel and innovative and set a new standard for how quays were constructed throughout the world afterwards. This diving bell has been turned into a sort of a micro-museum and you can now stand underneath it, read about its interesting history and try to imagine what it would have been like to be one of six workers working in this thing on the floor of the Liffey in the late 1800s. If you're anywhere near Sir John Rogerson's Quay, its definitely worth taking a few minutes to visit.

Dublin Port's 'Diving Bell' was used for almost 90 years to build the city's quay walls. The bell entered service in 1871 and was used in the building of the port's walls until 1958.

The Diving Bell that was used to build the River walls has been turned into an interactive walk through exibition , small but very informative.

The Diving Bell hosts a piece of Irish engineering history. In fact it is an Irish man that came up with this innovation. If you are looking for something to see on the south river bank, or if you are in the area, it is worth a visit.

Nice view by the Liffey river. Can be a good sight for photographers to indulge in or for a good stroll along the river on a warm day

Interesting part of Dublin history that this diving bell was restored and has a small taste of Dublin inside. It's free to go inside where you can find out more information about it.

This piece of industrial history gives you an interesting glimpse to the everyday life of a diving bell worker.

Dublin's Diving Bell offers a fascinating glimpse into the city's maritime heritage and provides a unique and immersive experience that transports visitors back in time.

Very interesting free exhibition, it was great to learn about the history of the bell.
