The baroque "Chapel of Merchants, Shopkeepers and Bankers" was built at the end of the 1600s. This lesser known architectural jewel still holds numerous original artworks. The most noteworthy of them is the Perpetual Calendar built by the engineering Giovanni Plana — a primitive computing machine that allows its user to look up details about any date between the years 1 and 4000. Powered by a small wooden crank, the intricate gears and chains put into motion the nine inscribed cylinders, The chapel is only open to the public on the weekends, when mass is held. If you are lucky, you can attend the occasional classical music concert and experience the building's impressive acoustics.

The monumental Masjid Nasional Al-Akbar is a spectacular modern mosque, one of the most imposing in Southeast Asia, let alone Indonesia itself. Access is open to visitors, and the top of one of its minarets offers spectacular views over the city (staff will guide you to the elevator on request).

The Venaria Palace is a former residence of the Savoy family just outside Turin. The palace is one of the most beautiful royal residences in Europe. As such, it is part of the UNESCO World Heritage list. Today it houses a big contemporary and fine art museum. You can admire the palace itself and the surrounding gardens, too. Large music events are often organised here, from classical music concerts to techno and house music festivals.
