As human dwellings evolve, so does the need for more sophisticated security measures to keep the occupants safe without interfering with their way of life and living experience. It becomes even more imperative that architecture practitioners inculcate practical security measures into every building from conception and follow up to ensure implementation. In Nigeria, however, the application of Crime Prevention Through Environmental Design (CPTED) has been limited due to some established factors. The study seeks to explore the architectural solutions to crimes and security challenges peculiar to Nigeria, through the application of CPTED theory. Specific focus was placed on Ilorin, Kwara State. Review of existing literature was employed to carry out this study. This study concludes that environmental criminology should be utilized at the planning stage of design to ascertain reasonably foreseeable crimes by looking at official and unofficial records and patterns. An accurate adaptation through architecture will help to prevent crime, reduce the fear of crimes and promote a sense of the communityenArchitecture, Crime Prevention through environmental design (CPTED), environmental criminology, SecurityArticle
