I noticed a tunnel from the US Capitol to the Library of Congress and decided to go over to take a look. You need to pre-book a free timed ticket to the library and there was a QR code at the entrance so I was able to get a ticket before walking down the corridor. It was easier to get in since it wasn't as busy as the main entrance. There was no security check to get to the Library but there was one heading into the US Capitol. The initial step into the hall was breathtaking. The vibrant colours and the carved stairwell was very beautiful. The roof paintings on the first and top floors were also quite nice. The top floor also had a gallery and Thomas Jefferson's Library. There is also a set of stairs which lead to a balcony in the main library. As I was leaving, I noticed there was a stall in the great hall where there was someone distributing the tickets for the main library. It is a free tour of the library and I was lucky enough to be able to get a ticket for a tour in the next 15 minutes. You wait at the meeting point with your ticket and then you get to go into the main library. The library was huge and standing in the middle of it was quite an experience. Lots of books and the interior was as beautiful as the main hall. There were also statues lining the top and the top of the columns label the sections within the library. It is definitely worth a stop if you are in the area to admire the beautiful interior.

Each and every detail in this building left me speechless. I would say that we were at the Library of Congress a good 2 hours just in awe with the architecture. If you ever find yourself in D.C and have an interest in architecture, I would highly recommend visiting this fascinating building.

What a beautiful place. Prebooked our visit (it’s self-guided, not a guided tour) and wandered around at our own place. Plenty of volunteers ready to answer any questions. We didn’t go into the research library itself, were advised not to bother as you queue for some time then only get a few minutes inside. You can go to the first floor and see from above. Well worth doing. We were there about an hour or so, it’s not a lengthy visit. But it is well worth exploring the smaller exhibitions to the sides. I believe they change regularly.

We as a group of friends visited the library . It is a must see of dc. Largest library in the world. Fantastic building.lots of things to learn. It takes less than two hours. Always there is a queue for entrance which takes 40 min. You should took free ticket online in advance.

The Library of Congress is a place less known than it should be. The experience of the visit is intense. The imposition of the building, from ceiling to floor, the finishing details, is an entire work of art. A well-organized visit, volunteers spread out to serve the public in English, and there is a glazed place on top, from where you can admire and photograph the Library. The photos are beautiful, but say much less than the live experience. No cost to visit. Many marble stairs, but there are elevators, the place is inclusive. Don't stop going.

The building is spectacular. While we were unsuccessful in getting a tour because the staff were not helpful, we lucked out by asking the many volunteer docents questions. They were a wealth of knowledge and offered lots of great tips about what to see in the exhibits.

Of course, the library's significance is important. But the building itself, how it was constructed, and the various details in the artwork tell a story about the mindset of the times. Jefferson's library is a must see, as is a walk through the actual gallery.

The Library of Congress areas that you actually get to see as a tourist reminded me greatly of Rome with its frescos, mosaic floors, paintings, etc. It is very elaborate. You only get to actually see the library from a windowed room above it, but it looks like an amazing place to study! Throughout the time we were there, we also got to see some exhibits on photographs and Thomas Jefferson's private library. You will need timed entry tickets, but they are free.

An imposing building that we could reach underground from the Capitol. The library is huge and spans several buildings. The Thomas Jefferson Building can be visited, with bookshelves and a rare Gutenberg Bible. The “Great Hall” with mosaics, paintings and an imposing curved marble staircase is very worth seeing. The “Main Reading Room” is located under a 23 m high dome. Mahogany tables are being worked on there. Access is restricted to Capitol staff.

A truly magnificent and spectacular place. I was very positively surprised. The collection he has, moreover, is up to scratch. No longer just see Thomas Jefferson’s personal library, but many other treasures, such as one of the few remaining bibles Gutenberg printed, or listen to a copy of the disc that travels on the voyager probe containing greetings in dozens of languages. Undoubtedly, a must from Washington
