Oltepesi Cultural Institute is in Mashuuru District, Kajiado County. It is in the East of Kajiado town, about 70 Kms,from Kajiado town and it is in West of Sultan Hamud, about 40 Kms.

The Institute is surrounded by four sub-sections of the Maasai, namely:

Ilkaputiei,Ildala le Kutuk,Ilmatapato and Iloitokitoki ( other people call them Ilkisonko but in the actual fact,Ilkisonko are in Tanzania).

The Institute as foresaid  is the brain child of Fr.Frans Mol,a Mill Hill Priest who has since retired and went back to Holland.The Institute is still young and can not support itself sufficiently. There are very few accommodation places  for our students or course participants.We still need to put up an underground tank to harvest rain water .but the resources are very scarce. When Fr.Mol left,there were only two small houses renovated but for now Fr. Karl Oberprantacher MHM has assisted in building two staff houses,one classroom,one self contained room,a big Library room,two kitchens,a pantry ,two washrooms for men and women one pit latrine divided for men and women with a bathroom,and  a big dinning hall.
