St. Andrews Cathedral is situated along Kenyatta Highway Thika opposite Thika High School.The Church moved from a small Church that was constructed during the colonial times in section 9 area in Thika Town, to its current site in 1970. For a long  period, the Christians had been worshiping in a Church hall which was outgrown by an increasing number of worshippers.

This prompted the Church leadership to initiate the current ongoing church project in the year 1997.

In order to achieve this objective, the Vicar -in-charge, the late Canon Samson Njuguna constituted a Building Committee of 12 members to spearhead the construction project.
