England boasts many architectural marvels, from domed cathedrals and towering skyscrapers to majestic castles and elegant Georgian manors. And the oldest surviving structure in the country is a must-visit for any history enthusiast.

Nestled in the heart of Canterbury stands the ancient Church of St Martin. Built upon Roman foundations, it incorporates Saxon features within its windows and overall structure, with Norman and Medieval modifications added over time.

Constructed prior to 597 AD, it holds the distinction of being the oldest church building in Britain still in use today. According to Heritage Calling, it's also the oldest surviving building in England, full stop.

The earliest section of the church was erected during the Roman occupation of Britain, although the original purpose of this part of the structure remains a mystery. It's unclear whether it served as a church or a mausoleum, reports the Mirror.

The building was later expanded to nearly its current size, with the nave - the largest part of the structure - becoming the first Anglo-Saxon construction made of mortared brick and stone instead of wood.

This Church of England parish church is also part of the World Heritage Site, alongside Canterbury Cathedral and St Augustine's Abbey, making it a key attraction in the city. Since 1668, this historic edifice has been part of the benefice of St Martin and St Paul, Canterbury, with both churches hosting weekly services.

Travellers from across the globe have been captivated by the revealed timber beams within St Martin's, alongside the elaborate stained glass features, extended nave and wooden seating, creating the sensation of journeying through history. One enthusiast remarked on TripAdvisor: "I visited early as the church opened, and I had a peaceful, excellent visit. Upon entry, I was greeted by a friendly employee who offered me a written guide of the church. The guide was easy to follow and had great, interesting information. The cemetery on the property was great for wandering and reading the graves as well!"

Given the church's rich heritage, the well-informed guides contribute significantly to making each visit truly memorable, complemented by its undeniable splendour and character. Another guest commented: "Given to the 6th-century Frankish princes, this beautiful building has a wonderful history.

"Guides were present from 11am and greatly helped appreciate the story behind the building and its lovely and slightly overgrown churchyard. Interesting people are buried there, too. Can look from this elevated spot down to its daughter church - the cathedral itself!"

Among those interred within St Martin's grounds are 19th-century evangelist William Cadman, artist Thomas Sidney Cooper, and Mary Tourtel, the mastermind behind comic book character Rupert Bear. Additional observers mentioned that guests can equally wander the site at their own pace, providing the freedom to explore thoroughly.

Another enthusiast shared on TripAdvisor: "The oldest church in mainland Britain, tucked quietly away, about 10 mins from the cathedral. Quiet and serene, maintaining the sense of a truly sacred space. There is a helper who will provide information or guide you, or you can explore independently. Not far from the Abbey, and worth the extra time."
