though frequent shipments." While during the 1880s the port served as a distribution point for rifles and ammunition to Shewa and Ethiopia (during this period, Arthur Rimbaud lived in the city), Tajoura's importance inevitably declined with the construction of the Ethio-Djibouti Railways, which connected Djibouti with the hinterlands. The railway began to carry traffic on 22 July 1901, was extended to Dire Dawa 17 months later, and finally to Addis Ababa on 3 December 1929. Djibouti The Djibouti government established various large-scale public works programmes to renovate the city. The Tadjoura port was modernized in 2000, at a cost of US $1.64 million. The work was described as part of the government's effort to help the economic development of the districts of Tadjourah, Obock, Ali Sabieh and Dikhil. The new Port of Tadjoura has been built to mainly focus on general cargo, such as livestock, sesame, frankincense, fertilizers and grain, at the cost of US $90 million. Initially the port has been developed in the aim to transport mainly potash from Ethiopia's Afar Region, while the mining is not yet developed. Besides that the port has a potential to provide for northern Djibouti and to its closest outlet for Ethiopia's Afar and Tigray regions. Compared with the traditional route from ports in Djibouti via Galafi, the new road (RN-11) from Tadjoura to Balho is shortens the driving hour significantly. Climate Featuring an arid climate, the town sees on average 186 mm (7.31 in) of rainfall per year. Average temperatures range from in winter to in summer.
