The National Museums of Kenya (NMK) celebrated their 100th anniversary in 2010. The museum was originally started by colonial settlers and naturalists who were looking for a space to store their many natural specimens. A core function of the museums, according to the "About Us" section of their website, is to "to identify, protect, conserve and transmit the cultural and the natural heritage of Kenya." Visitors should check out the "Interactivity" link on the left hand menu. There is a "blog", "map", "virtual tours", "children's section", and an "online gallery". The "map" section shows the sites of the regional museums and historic sites under the umbrella of the NMK, and visitors can learn the details of the museum or site by scrolling over the yellow or red markers and clicking on them. The Kapenguria site, for example, is where the "six most influential leaders in the struggle for independence were detained." Included as part of the museum are the renovated prison cells, the Pokot homestead, and galleries that explain the political development of Kenya from "pre-colonial Kenya, slavery, the arrival of Europeans, African resistance to colonial rule, and activities of pioneer nationalists."
