Located in the heart of Old Town, this 17th-century Jesuit church is another Baroque gem of Kaunas. It also has a terrace with a stunning view of Town Hall square.

Portland is home to the nation's largest wooded urban park: a short hike in, and you'll barely believe civilization is only steps away. 70 miles of trails traverse the forest overlooking the Willamette River, and although you'll have nature all to yourself at times, you're sure to also run into Portlanders out on a jog or walking their pups — prepare to be greeted with a friendly "hello." If you have time, hike up to Pittock Mansion, a French Renaissance-style château that was once occupied by the family of publisher and businessman Henry Pittock, and has now been turned into a historic house museum open to visitors. Another popular hiking destination is the so-called 'Witch's Castle' (pictured) — remnants of an abandoned stone house overgrown with moss, used by local students as a Friday night hangout location. The place is steeped in a bit of mystery, and although there is no record of any ties to witchcraft, its original dweller is rumored to have been the first person in Oregon to be sentenced to execution for murder in 1859.

Housed in a beautifully restored Jesuit school building from 1612, the Museo Naval del Caribe covers in some detail the 500 years of Cartagena's maritime history. You'll find sunken ships, cannons, ship's bells, muskets, and other treasures here. The descriptions are in Spanish, so it's a good idea to get a guided tour.

West of the city of Kathmandu lies this cluster of temples, shrines and other religious structures, one of the oldest and holiest places in the whole country, revered by Buddhists and Hindus alike.
