A collection of landmark Portsmouth buildings

Although the City of Portsmouth lost many of it's greatest building due to air raids and bombing during The Blitz as well as some to over zealous town planning, there are still some great buildings to be seen around the city if you know where to look, some historic and some modern. We have gathered together a collection of these buildings here. We hope that you agree with our choices, architectural opinions are of course a matter of personal opinion.

Some other important Portsmouth buildings are already covered elsewhere on this site such as St Thomas' Cathedral and Portsmouth Guildhall so are not included here. The long demolished Tricorn Centre can be found here.

If you think we have missed an important building that you love or admire, then please let us know at and we will check it out.
