The Library of Congress is the largest library in the world, and its three buildings — the Thomas Jefferson, James Madison Memorial, and John Adams — are well worth exploring. Free tours show off the architecture and highlight the rare collections, while exhibitions, gallery talks, concerts, and lectures give visitors plenty to see and do.

The Jordan National Gallery of Fine Arts offers a refreshing counterpoint to Amman’s ancient ruins. It showcases contemporary works from across the Islamic world in two airy buildings that flank a sculpture-dotted park. Founded in 1980 under royal patronage, its collection spans 2,000 pieces: from provocative Palestinian installations to delicate Sudanese weavings. Be sure to check the rotating exhibitions in Building 1. Building 2 anchors the experience. Start at the ground-floor, then work your way up through bold Jordanian abstracts before rewarding yourself at the top-floor café. Its terrace overlooks Jabal al-Luweibdeh’s artsy rooftops, perfect for reflecting over mint tea after browsing the art library’s curated books. Free from crowds (and mercifully air-conditioned), it’s where Amman’s creative pulse feels most immediate.

Rock Creek Park has been a green space in D.C. since 1890. It’s a good spot to escape the city, walk or bike along trails, and enjoy nature without leaving the urban area. Keep an eye out for squirrels, birds, and other wildlife as you wander through the woods or along the creek.

The Supreme Court building, completed in 1935, is open to the public for self-guided visits. On the ground floor, you’ll find exhibitions about the Court’s history and role in government, and on the first floor, you can see the courtroom where cases are heard. There’s also a short educational film, and at certain times, you can attend lectures or oral arguments if the Court is in session.
