 Cheap Travel

 You can pay a fortune to travel around the world. Or you can pay nothing at all. Here are some places you'll never regret visiting. They won’t cost you a dime.

 The British Museum, London(U. K.)

 You need to come here to see the Egyptian mummies, the ancient Greek marbles and so many other treasures. It's open every day, and unlike most other attractions in England that cost an arm and a leg, it's completely free.

 National Mall, Washington D. C. (U.S.A.)

 You can walk a pathway from the Lincoln Memorial to the severe Vietnam Veterans Memorial and to the Washington Monument with other sights in between. Do you know you can go up in the elevator to the top of the Washington Monument? Tickets are free, but pay a small fee to reserve them in advance to avoid being disappointed.

 Notre-Dame Cathedral, Paris(France)

 This great treasure of the world simply can't be missed. The great stained-glass rose window alone is worth the visit. The Sunday Mass with the Gregorian chant was like stepping back in time. Admission is free every day, but you're welcome to leave a donation. There are also free tours a few times each week. You’ll pay extra for tours of the bell tower or the crypt.

[ Tips:] The Notre-Dame Cathedral was greatly damaged by a massive fire in April 2019. Please visit notredamedeparis. fr/en/ for more information regarding future visits to the cathedral.

 National Museum of Ireland, Dublin and Mayo(Ireland)

 Want to see bog bodies, gold ornaments, Viking artifacts and learn about rural Irish life? All four branches of this museum are free to visit, including museums devoted to archaeology, natural history, decorative arts and history and country life. The museum of country life in Turlough Park, Mayo, is devoted to Irish rural traditions, while the natural history museum is especially famous for its collection of insects.
