The annual Arthur's Day celebrations took place in more than 50 countries across the world, and Jamaica's was at the National Indoor Sports Centre in St Andrew.
At this event, Guinness fans celebrated the extraordinary work of founder Arthur Guinness, and the three Jamaican awardees, announced at the event.
Each awardee received a cheque for $1.5m, from the Arthur Guinness Fund, to enhance their social projects and make a positive impact on their community.
The fund supports people from around the world who roll up their sleeves and make great things happen in and for their communities.
These people are the believers, thinkers, dreamers, innovators and doers who lay the foundation to build stronger communities for tomorrow's generation.
Lyden Buchanan's Bridging the Gap project, Wayne Williams' Mike Town Horticultural Skills Training and Havalee Henry's Mobile Clinic emerged the recipients of the fund and the much-needed money support to improve or continue their projects.
Henry has been utilising the mobile clinic for delivery of free health-care to underserved communities in Jamaica.
Mike Town Horticultural provides training for youths between the ages of 18-25 in the community, and originated in 1998 as an outreach mission of the Moravian Church.
The Bridging the Gap project seeks to provide transitional support services in housing, mentorship, and continuing studies for males who have matured out of the tertiary child-protection system and have no family support for reintegration into society.
Williams said, "Not only will this investment I've received allow me to make a difference in more people's lives, but to feel the support for the work that we do, is an honour."
The Arthur Guinness Fund was established in 2009 by Guinness and, to date, it has committed more than €8 million to entrepreneurs around the world, in a variety of projects designed to benefit grassroots communities.
