Be prepared to have your mind bent, blown and rewired as you walk into the Lange Voorhout Palace where the illusory work of famous graphic artist M.C. Escher is exhibited. The palace is home to such legendary Escher paintings as 'Air and Water' in which birds are blended into fish and 'Waterfall' in which water appears to flow upwards instead of down. There are interactive experiences on the second floor, dedicated to the Eye of Escher where guests are encouraged to solve some of Escher’s most perplexing mysteries, including the impossible Penrose Triangle. On the third floor, there is a large-scale optical illusion where adults can appear to be children and vice versa. Audio tours and guided tours are available and there are additional temporary exhibitions taking place on occasion.

This excavation rivals the famous sites of Pompeii. Once home to around 400,000 residents, ancient Ephesus was built around the temple of Artemis — another marvel among the Seven Wonders of the Ancient World. The ruins we see today primarily hail from the Roman era. The remnants of the Temple of Artemis stand outside the main ruin area, while the hill above is graced with the cathedral of Saint John, said to be the final resting place of the evangelist. Legend holds that Saint John lived in Ephesus alongside the Virgin Mary.

Built to commemorate the coup of 1994, the unmissable cream-colored structure is a great vantage point from which to take in Banjul in its entirety. There is a small museum on its second floor, containing traditional Gambian crafts, artwork, clothing, and even historic weaponry.

The Inner City can be defined as the metropolis of Copenhagen, which encompasses the city's oldest district with pretty narrow streets and original houses. The city centre is full of shops, bars, restaurants, parks, numerous canals and, of course, Nyhavn, the colourful harbour of Copenhagen. The main street of Inner City is Strøget, which goes from the town hall square to Kongens Nytorv. Strøget is always frequented by a myriad of street performers, but do not forget to take a trip to the pretty side streets like Frederiksberggade, Nygade and Vimmelskaftet.
