The Mausoleum in Monastir!

Monastir a seaside town near its neighbouring resort of Sousse, is known for the burial place of ex-President Bourguiba. If you want to visit Monastir it's about a 2-hour drive from Tunis , or take train from Tunis to Sousse and then another train to Monastir. It's a nice day out! I've been there three or four times.

Here is more information:

Monastir was the birthplace of Habib Bourguiba, the first president of independent Tunisia. The Mausoleum of Habib Bourtguiba was constructed in 1963 and highly distinguished by its huge ribbed golden dome and the twin thin Minarets with magnificent Italian Limestone. Within the tomb, stand the cenotaphs of all the family members of Buorguiba. One can climb the flight of stair steps leading to the top of the mausoleum to have a close view of the dome and overall view of the surrounding area of the tomb.

It is open to the public until 3pm and entry is free.
