This beautiful building in the heart of historic Canterbury has been a landmark for pilgrims and visitors since the Middle Ages. With more than 1,400 years of history, this impressive cathedral is still an active, working church and welcomes both worshipers and tourists alike. Discover the striking architecture, magnificent gardens and fascinating history of the cathedral with a guided tour and enjoy a coffee and snack from the kiosk as you stroll through the grounds.

During the summer, you can also visit the new exhibition, Making History: Church, State and Conflict, in the cathedral’s crypt.

2. Viking Coastal Trail, Thanet

This stunning 32 mile route takes keen cyclists along the Thanet coast, visiting spots such as Margaret, Broadstairs and Ramsgate on the way.

Visit quaint villages, dramatic marshland and hidden bays and, if you get tired, take a break at one of Thanet's many pubs, bars or restaurants and watch the sunset over the beach.

One of Kent’s most unique and intriguing attractions is the Shell Grotto.

Make up your own mind as you venture down into this stunning and curious work of art.

10. Rochester Castle and Cathedral

With these two huge attractions just a stone’s throw from each other, it makes sense to visit the two together and soak up as much of Rochester’s history as you can. The cathedral, which towers over the centre of the town, is the second oldest in England. Founded in 604, this working place of worship has many fascinating collections to browse, some dating as far back as the Middle Ages. Rochester Castle, on the other hand, began life as a Norman tower-keep in the 1100s and still stands today as a reminder of the town’s history.

During the summer, you can head inside the cathedral and see the Big History exhibition, which uncovers the background and archaeology behind the cathedral and looks at the changes that have influenced life at the site over the last 1,400 years.

Rochester Castle is on Castle Hill and Rochester Cathedral is at The Precinct, both in Rochester town centre.

The castle is open during the summer from Tuesday to Sunday, 10am to 6pm. Book online here.
