Though a very small oasis, Tit is famous because of the battle of Tit.
During the second part of the XIXth, the French tried to take control of the Sahara. The Tuaregs opposed violently. On February 16th 1881, they slaughtered the column led by Colonel Flatters at Tin-Tarabin.
On May 7th 1902, the Kel Ahaggar Tuaregs of Aménokal Moussa Ag Amstan (the Aménokal is the «king» of the Tuaregs) were defeated in Tit by Lieutenant Cottenest and more than 200 were killed. After that defeat, The Aménokal agreed to put an end to the battles against the French and to accept the French rule on the Sahara.
This is the road sign that was standing along the road in 1977. It was already an old one and I suppose it is not there anymore, though, who knows!
It gives the distance to various cities northwards:
Paris, 3655 km
Algiers, 2017 km
El-Goléa, 1117 km
In-Salah, 645 km
Tamanrasset, 45 km
Agadès, 940 km
Other destinations have been added by visitors such as Amsterdam, 6500 km (I doubt this is right), Argentina 14,000 km (?), Heidelberg, 7,000 km (?), Gerona 3,300 km and Tit, without any distance as the road sign was standing at the cross road for Tit, a few kilometers away.
