A round-trip cruise with KD is one of the best ways to take in Frankfurt’s skyline from the water. The one-hour route along the Main River passes landmarks like the Römer, the Museum Embankment and St Paul’s Church, with commentary about the city’s past and present.

For a fun way to see Frankfurt, hop on the Ebbelwei-Express, a vintage tram that rattles through the city on weekends and public holidays. On board, passengers are served apple wine (or juice) and a bag of pretzels while local music plays in the background. The hour-long ride takes in many of Frankfurt’s main sights, and tickets are sold by the conductor. You can board at any of the tram stops along the route, but the ticket covers one full loop without hopping off and back on again.

North of Nottingham, in Newark, you can find the The Holocaust Centre. This place says they want to promote an “understanding of the roots of discrimination and prejudice and the development of ethical values, leading to a greater understanding within society”. You will definately not leave the place unmoved.

Constructed around the Church of the Holy Sepulchre, in the north-western part of the Old City, the area is home to several Christian sights. Few houses can be found here — it's mostly about religious buildings, educational facilities, and a plethora of cafés, restaurants, and shops. The streets are packed with vendors. It is especially worth exploring the area of Mauristan, teeming with shops and colourful stalls. Used as a market during the Roman Empire, the area hosted churches and hospices during the Crusades (in Persian, "Mauristan" means hospital).
