Used a backdrop for weddings, the Loretto Chapel is one of Santa Fe's oldest and most dear attractions. Formerly a Roman Catholic church, it now serves as a museum and wedding venue. Perhaps beyond its grand beauty and elegance, Loretto Chapel's continued allure lies in its mysterious spiral staircase. Both the identity of its builder and the stunning physics of its construction - there were no supports holding it as it spirals into the choir loft - remain a mystery. Legend says that St. Joseph himself made it, as the man who did build the staircase disappeared before the nuns were able to pay him, and the wood used was not native to the area. It is a stunning salute to the science of physics and the hearts of believers.

The region of Halkidiki lies southeast from Thessaloniki. It is known for its jutting peninsulas, Mediterranean forests and sandy beaches in warm, sheltered bays. The region is often described as having three 'legs', the Kassandra, Sithonia and Athos peninsulas. Kassandra, the westernmost peninsula, is the most developed, offering modern resorts and nightclubs. Sithonia, also known as Longos, offers over a 100 beaches, cute villages and is a popular destination for families. Athos is an important centre of the Eastern Orthodox church. Its main point of interest, Mount Athos, is home to 20 monasteries.

Your visit to Utrecht won't be complete without the iconic Dom Tower in your itinerary. Dating back to 1382, this monumental Gothic tower is visible from across the city, hence it stands as Utrecht's symbol and a must-visit attraction. Soaring to a height of 112 metres, it holds the distinction of being both the tallest structure in Utrecht and the tallest church tower in the Netherlands. The tower was originally connected to the Dom Church; however, after collapsing in 1674 due to a summer storm, both tower and church were rebuilt separately. Currently, there are various guided tour options available at the ticket shop.
