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.

Tammerkoski is a channel of rapids in Tampere. The city is nestled between Näsijärvi and Pyhäjärvi, two lakes with 18 metres of difference in level, which gave rise to the installation of several dams and power stations in the 19th century. An exhibition on the city's industrial past is also on at the Vapriikki Museum adjacent to the bridge.
