The Castle Keep in Newcastle is one of the finest of its kind surviving in Britain today. It is an ancient monument and a Grade 1 listed building. It sits upon ground previously occupied by the Roman fort Pons Aelius, an Anglo-Saxon cemetery and a Norman Motte and Bailey Castle from which the City takes its name.

Once Shenzhen's tallest skyscraper, Di Wang Building is more than just an architectural feat—it’s a symbol of the city’s rapid growth. Take a 50-second ride to the 68th-floor observation deck, where you'll be treated to panoramic views: Shenzhen’s ever-expanding skyline on one side and a glimpse of Hong Kong on the other. Once holding the world record for construction speed (an impressive 2.5 days per floor), this building is a testament to the city’s ambition. Although newer skyscrapers now tower over it, Di Wang remains a must-visit for those wanting a bird's-eye view of Shenzhen's dynamic urban landscape, especially when the sun sets and the skyline lights up.

Stretching 250 metres long and 4 metres wide, Chung Ying Street is one of the most fascinating places to cross from Hong Kong into Shenzhen’s Shekou town. One side of the street belongs to Hong Kong, while the other is in Mainland China—standing in the middle feels like a unique step between two worlds. The Chung Ying Street Historical Museum offers a deep dive into the history behind this border crossing. For those looking to shop, the street is a popular tax-free zone. However, it's important to be cautious as counterfeit goods are known to circulate here. A special permit is required to access the street.
