The city is the only island city in Britain, and dates from around 1180.  It was awarded its first Royal Charter by Richard the Lionheart in 1194, and since then it has played a vital part in many historic events, including the Battle of Waterloo and the D-Day landings.

Learn about the recent past at the D-Day Museum, or take a look back in time at 16th century Southsea Castle.  Just along from the castle, the Australian Settlers Monument commemorates the first European settlers to leave for Australia from Portsmouth in 1787. You can see Lord Nelson’s famous flagship HMS Victory at Portsmouth Historic Dock, and the oldest dry dock in the UK is also home to the Tudor carrack Mary Rose and HMS Warrior 1860.

The Spinnaker Tower at Gunwharf Quays dominates the harbour area, and is one of the city’s most striking landmarks.  It soars 557 feet into the air and the view from the top is spectacular.  Try the Sky Walk or enjoy a coffee at the cafe.  There’s plenty to appeal to all ages in the city, and the Blue Reef Aquarium boasts over 40 exhibits, including a giant tropical reef tank with a walk through tunnel and an otter holt.

Thanks to Southsea beach and seasonal attractions such as the Spinnaker Tower which is open daily during July and August, from May till September is the most expensive time to visit.  The cheapest time is undoubtedly from September onwards, with the exception of the Christmas and New Year holiday period.  Since the city is beautiful in spring from March till May, and in autumn from October to November, low season is still an excellent time to plan a trip.
