What the Capitol Building Is and Where to Find It

The U.S. Capitol Building is the home of Congress — the legislative branch of the federal government — and sits on Capitol Hill in Washington, D.C. The building itself is one of the oldest federal structures still in use, and it is open to the public for tours. The Capitol is located at First Street SE, between Independence Avenue and Constitution Avenue, in the heart of downtown D.C., roughly two miles east of the White House.

The building is when ready recognizable by its large dome, which you can see from many points around the city. Inside, you will find the chambers where the Senate and House of Representatives meet, as well as offices, committee rooms, and public galleries where visitors can watch Congress at work. The Capitol also contains historical artwork, statues, and architectural details that span more than two centuries.

Key Takeaways

  • Visitors can tour the Capitol Building for free, but you must book a tour in advance through the Capitol Visitor Center or your representative's office.
  • Tours typically last one to two hours and cover the Rotunda, National Statuary Hall, and other major spaces, but do not include active congressional chambers.
  • If Congress is in session, you can watch proceedings from the public galleries without a separate tour reservation.
  • The Capitol Visitor Center, located below ground on the east side of the building, provides information, restrooms, and a cafeteria.
  • Security screening is required for all visitors, so plan to arrive early and bring a valid photo ID.

How to Book a Tour of the Capitol

The easiest way to book a tour is through the Capitol Visitor Center's website at visitthecapitol.gov. You can reserve a tour slot up to 60 days in advance. Tours are offered Monday through Saturday, with multiple time slots throughout the day. You will need to provide the names of everyone in your group and at least one valid photo ID for each person.

If you prefer to book by phone, you can call the Capitol Visitor Center at 202-226-8000. Staff there can answer questions about tour availability and help you find a time that works for your schedule. Tours are free, and no payment is required to reserve a spot.

Another option is to contact your U.S. Representative or Senator's office directly. Many congressional offices offer their own guided tours, which are also free and sometimes include special access or additional information. You can find your representative's contact information on House.gov or Senate.gov.

What to Expect During a Standard Capitol Tour

A typical Capitol tour lasts between one and two hours and covers the major public spaces of the building. You will walk through the Rotunda, the large circular chamber beneath the dome, where you can see historical paintings and sculptures. The tour also includes National Statuary Hall, where each state has placed two statues of notable historical figures.

Tours visit the corridors and galleries that surround the building's main chambers, but you will not enter the active Senate or House chambers during a standard tour. If you want to watch Congress in session, you can visit the public galleries separately — those do not require a tour reservation, only a security screening.

Your tour guide will explain the history of the building, point out architectural features, and answer questions about how Congress works. The pace is moderate, with some standing and walking, so wear comfortable shoes. The building has stairs, but elevators are available for those who need them.

Watching Congress from the Public Galleries

If Congress is in session, you can visit the public galleries to watch the Senate or House at work without booking a tour. The galleries are open to the public during legislative sessions, and entry is free. You will need to go through security screening, which includes a metal detector and bag check.

To find out whether Congress is in session, check Congress.gov or call the Capitol Visitor Center. Sessions typically occur during the week, though the schedule varies by season. The Senate and House galleries are located on opposite sides of the Capitol, and you can visit one or both during the same trip.

Visitors in the galleries must follow strict rules: no photography, no recording, no talking, and no electronic devices. Bags are subject to search, and large bags may not be permitted. The galleries can be crowded during high-profile votes or hearings, so arriving early increases your chances of getting a seat.

Security Screening and What to Bring

All visitors to the Capitol must pass through security screening before entering. You will go through a metal detector and your bags will be searched. The process is similar to airport security but usually moves faster. Plan to arrive at least 15 to 30 minutes before your tour time to allow for the screening process.

You must bring a valid photo ID — a driver's license, passport, or state ID card will work. Children do not need an ID, but they must be accompanied by an adult. Leave prohibited items at home or in your hotel: weapons of any kind, explosives, sharp objects, and large bags are not permitted. A small backpack or purse is usually fine.

The Capitol Visitor Center has lockers where you can store items you cannot bring into the building, though space is limited. It is better to travel light and avoid checking bags if possible. The building itself has limited coat check facilities, so dress for the weather.

Getting to the Capitol and Parking

The Capitol is accessible by public transportation. The Metro (Washington's subway system) has two stations near the Capitol: Capitol South on the Blue, Orange, and Silver lines, and Union Station on the Red line. Both are within walking distance. If you are driving, street parking is available but can be difficult to find, especially on weekdays when Congress is in session.

Several paid parking garages are located nearby, including the Union Station garage and lots on the surrounding streets. Parking rates vary, but expect to pay $10 to $20 for a few hours. The Capitol Visitor Center has limited visitor parking, but it fills quickly.

If you are visiting from outside D.C., consider staying near Union Station or a Metro-accessible hotel. The Capitol is straightforward to reach by train or subway, and public transportation is more convenient than driving and parking in downtown D.C.

Hours, Closures, and Special Circumstances

The Capitol Visitor Center is open Monday through Saturday, 8:30 a.m. to 4:30 p.m. Tours typically run from 9 a.m. to 3:30 p.m., with the last tour departing around that time. The building is closed on Sundays and federal holidays. Hours may change seasonally or due to special events, so check visitthecapitol.gov before you visit.

The Capitol may close to visitors on short notice for security reasons, state funerals, or other official events. If you are planning a visit, confirm that the building is open before you travel. The Capitol Visitor Center website displays current closure information and any changes to tour schedules.

During the winter months, Congress often takes a recess, which means fewer legislative sessions and potentially fewer crowds. During the summer, school groups and tourists fill the building, so tours can be busier. If you prefer a quieter visit, consider going in the fall or winter.

Frequently Asked Questions

Can I bring my children on a Capitol tour?

Yes, children of all ages are welcome on Capitol tours. They do not need a photo ID, but they must be accompanied by an adult at all times. Tours can be long and involve standing and walking, so consider your child's age and stamina. The Capitol Visitor Center has family restrooms and a cafeteria if you need a break.

What if I cannot book a tour in advance?

If you arrive without a reservation, you can still visit the Capitol Visitor Center and watch Congress from the public galleries if it is in session. However, you cannot take a guided tour without a prior booking. Tours often fill up weeks in advance, especially during peak tourist season, so planning ahead is important.

Can I take photographs inside the Capitol?

Photography is permitted in most areas of the Capitol during tours, including the Rotunda and National Statuary Hall. However, photography is strictly prohibited in the public galleries where Congress meets. Check with your tour guide about specific restrictions in different areas.

How long does a Capitol tour take?

A standard guided tour lasts between one and two hours, depending on the size of your group and how many questions are asked. If you visit the public galleries separately to watch Congress, add another 30 minutes to an hour. Plan for at least three hours if you want to do both a tour and visit the galleries.

Is there a cost to visit the Capitol?

Tours and visits to the Capitol are completely free. The Capitol Visitor Center also offers free information and restrooms. The only costs you may incur are for parking, meals at the cafeteria, or transportation to get there.
