End of Europneumo2022 meeting.



Europneumo2022 main venue, The Museum of Liverpool

The Museum of Liverpool is a purpose-built landmark building on Liverpool's famous waterfront. Opened on 19 July 2011, it is the largest National Museum to be built in the UK in over 100 years, and is situated on a UNESCO World Heritage Site next to Liverpool's famous 'Three Graces'. The building features huge projecting windows at either end, one facing the city centre and the other out across the River Mersey. The limestone panels that surrounds its facade are shaped as zig-zagging diamonds, creating the illusion that the building has been stretched. Inside the building, a large staircase spirals up through an atrium at the heart of the museum, leading to three floors of galleries that exhibit Liverpool's social history and popular culture.

Networking events

Opening ceremony at the Liverpool Town Hall - Tuesday 31st May 2022

We will welcome our Europneumo2022 delegates at the prestigious Liverpool town Hall, home of The Lord Mayor of Liverpool. Built in 1749 and designed by John Wood, this Grade 1 listed building is recognised as one of the finest surviving town halls of the 18th century and a masterful example of Georgian architecture.

Gala dinner at the Oh Me Oh My Restaurant - Wednesday 01 June 2022

Oh Me Oh My is located in the West Africa House, opposite the city’s iconic Three Graces, at the heart of historic downtown Liverpool. Built in the 1920s by Briggs, Wolstenholme and Thorley, the building was home to the former bank of West Africa. With its beautiful roof garden, located on the 8th floor of the building, Oh Me Oh My will host Europneumo2022’s gala dinner. Dress code: business casual.

River Explorer Cruse on the Mersey River - Thursday 02 June 2022

Our Europneumo2022 delegates will be invited to experience a 90-minute sightseeing cruise and learn about the fascinating history of the River Mersey while sailing along Liverpool’s UNESCO World Heritage Waterfront from the deck of the world-famous Mersey ferry.
