You can’t really miss it—Florence’s cathedral (Cattedrale di Santa Maria del Fiore) dominates the skyline with that massive red-brick dome. Construction began in the 13th century and continued for nearly 150 years, which is evident in the diverse styles. The outside is covered in pink, green and white marble—oddly beautiful up close. Inside, check out Vasari’s Last Judgment fresco under the dome. If you’re up for the climb (and it is quite a climb), the view from the top is worth the leg burn.

Discovery Green is Houston’s go-to urban park for outdoor fun, events, and community gatherings. Located in the heart of downtown, it features open lawns, a lake for kayaking, public art installations, and a playground for kids. Throughout the year, the park hosts everything from live concerts and fitness classes to outdoor movie nights and seasonal ice skating. With on-site restaurants and plenty of spots to relax, it’s a great place to take a break from the city buzz. If you're looking for more green spaces, Hermann Park and Sam Houston Park offer a mix of history and nature downtown, while the sprawling Memorial Park sits just west of the city center.

The Basilica of the National Shrine of the Immaculate Conception is the largest Roman Catholic church in the U.S., with a striking interior of mosaics, chapels, and domes. Free guided tours are available and give a good sense of its history and architecture.

Hermann Park is one of Houston’s most beloved green spaces, offering a perfect mix of relaxation and outdoor activities. Whether you’re looking to jog, bike, rent a paddle boat, or just stretch out on the grass, this 445-acre park has something for everyone. Stroll through the peaceful Japanese Garden, catch a free performance at the Miller Outdoor Theatre, or visit the Houston Zoo, home to over 6,000 animals. Birdwatchers will love the park’s bird island, while golfers can hit the links at the historic Hermann Park Golf Course.
