La Martiniere Extra-Curricular Organization (LEO) is an umbrella group made up of representatives of the different Co-Curricular Activity (CCA) clubs that function in the College. The members of LEO see themselves in the role of leadership as lions. They have chosen, for their inspiration, the ubiquitous lion emblem that embellishes the monument Constantia, which is also the name of this event. The apex of the monument Constantia bears a unique crown, which contributes to the image of the crowned lion that is the mascot for Constantia.

Constantia 2023 is a four day-long event consisting of over 26 competitions in various co-curricular activities. Commencing in La Martiniere College in 2012, Constantia 2023 is the eleventh iteration of the event which is an opportunity to bring young people together in a controlled environment to compete against each other and to recognise each other’s talents. The competitions are broadly Technical, Literary and Business-oriented.
