The gardens evolved into areas specifically built for people to find health after it was discovered that the natural or designed environments play an essential part in expediting the healing time. Many studies conducted today show that gardens specially designed for therapy have significant results on user groups. Therapy gardens are gardens that are created to relieve stress and pain while also mentally, physically, and spiritually strengthening individuals who are suffering from psychological or physical issues. Since the Middle Ages, these gardens have been used as therapeutic spaces, and they have now become an important feature of hospitals, nursing homes, and rehabilitation facilities. Within the scope of the study, therapy gardens were examined in detail in all aspects. The principles to be considered in therapy gardens for children and the elderly people were revealed. Also some plant species that can be used in therapy gardens were given. As a result, it was emphasized that therapy gardens should be created within the scope of general design principles in order to reveal the expected benefits from them.
