Biennials are art exhibitions that occur every two years, showcasing contemporary works from various artists around the world. These events often feature a wide range of artistic mediums, including painting, sculpture, installation, and performance art. The goal is to present innovative ideas and trends in the art community, allowing artists to gain visibility and engage with a broader audience. One of the most famous biennials is the Venice Biennale, which started in 1895 and has become a significant platform for international artists. Other notable biennials include the Whitney Biennial in the United States and the São Paulo Biennial in Brazil, each contributing to the global dialogue on contemporary art.
