The capitol of Tunisia is Tunis.
Here's a little extra info about Tunisia just in case you would like to know:
Situated on the Mediterranean Sea, it is the northernmost African country, and the smallest of the nations situated along the Atlas mountain range, bordering Algeria, to the west, and Libya to the south east.
Tunisia is a land full of culture, historical significance, and beauty. It has been under the rule of Phoenicians, Romans, Arabs, Berbers, Ottomans, Beys, and French. Tunisia gained her independance from France in 1956 and elected it’s first president, Habib Bourguiba in 1957. Bourgiba placed strong emphasis on economic and social development, especially education, the status of women and the creation of jobs. In 1987 Bourguiba was deposed by his prime minister, Zayn al-Abidin bin Ali (Ben Ali), who is still the current president.
The official language is Arabic, with French being the official language of commerce. English is also very widely spoken, and in the tourist areas you will find people who speak German, Spanish, and Italian.
Here are some great attractions that are located in the capitol:
THE BARDO MUSEUM. In the suburb of Le Bardo is the Bardo National Museum, which has the world's largest collection of Roman mosaics and other antiquities of interest from Ancient Greece, Carthage and from the Arab period, and it ranks with the Egyptian Museum in Cairo as one of the two great museums of North Africa.

SIDI BOU SAID. The town is a tourist attraction because it is known for the extensive use of blue and white colors (the traditional colors of Tunisia) all over the town. All kinds of souvenirs can be bought in the main street. There is the traditional High Coffee there which is worth a look. My favorite is a coffee that overlooks the marina. It has fantastic views and a wonderful ambiance.
THE MEDINA. Just going there you can feel the history come to life. The streets are buzzing with shoppers and sellers. The medina itself contains around 700 monuments, including palaces, mosques, mausoleums, madrasas and fountains dating from the Almohads and the Hafsids periods.
DAR BEN ABDALLAH. A small but interesting museum within an 18th-century palace in the medina, covering the everyday life of a rich merchant in the Ottoman era.
ZITOUNA MOSQUE. The largest mosque in Tunisia. This Aghlabite mosque dates back to the 9th century. Modest dress is essential, and non-Muslims can only enter the courtyard, not the mosque itself.
PORT DE FRANCE. It is comprised of architecture and decoration from many different styles and periods and is believed to stand on the remains of a Roman theater as well as the tenth century palace of Ziadib-Allah II al Aghlab.
CATHEDRAL OF ST. VINCENT DE PAUL. It is located in downtown Tunis. It is a grand church situated in between shops and coffees.
DOWNTOWN TUNIS ITSELF. Here you can see the French influence on Tunisia as many of these old buildings are built in French style. It also is home to a beautiful giant clock tower that is illuminated at night.
LA MARSA. It is a coastal town not far from Tunis. It is a popular vacation spot for many middle class Tunisians, being one of the only accessible beaches in the capitol.
THE NORTH AFRICAN AMERICAN CEMETERY. This is the resting place for many Americans who fought in WWII and other wars around that region. I was impressed not only by the size, but by how beautifully kept and well maintained the cemetery was.
BIZERTE. I know it's not in Tunis, but it's only about a 45 minutes to an hours drive away, and it is gorgeous! This is where many of the residents of Tunis come for their summer escape to the beach. It is the northern most point of Africa and because of that, the majority of the city is bordered by the Sea. The beaches are pristine, and it offers some great restaurants and peaceful moments.
