Eastney Beam Engine House

The Eastney Beam Engine House is a red brick Victorian building that housed two large steam engines made by James Watt & Co. These machines pumped sewage across Portsmouth using mechanical power and rotating flywheels.

Built in 1887, this building became part of Portsmouth's modern sewage system designed to control pollution and disease. It operated successfully until newer technology replaced this approach.

The building shows how cities solved public health problems through large-scale engineering during the industrial boom. You can see how 19th century engineers tackled everyday challenges using steam power and mechanical innovation.

The museum opens to visitors on the last weekend of each month, when volunteers demonstrate how the steam engines actually work. Be prepared for steep stairs and tight spaces if you want to see the machinery up close.

The building nearly disappeared before it was saved in 1980 through the efforts of volunteers and local authorities. Today you can see how the restoration brought this industrial landmark back to life with the machinery running again.
