Jaume Plensa is a leading artist who pioneers public art that engages with the public, and his works are open to the participation and interaction of all viewers. Viewers can enter his works to take pictures, stroll around the sculptures, and take breaks while enjoying refreshments. Jaume Plensa establishes the concept of public art by presenting works that communicate with viewers in this way, and pioneers his own unique series of works. ⟨Children’s soul⟩ is one of a series of works that create shapes with sculpted text, and within his work, you can find various letters. He believes that 'letters' are the most beautiful material that best reveals culture, and he tries to incorporate that material into his work.
