In a recent feature for 'Ringvaade', the Kumu Art Museum's chief engineer, Hendrik Vahter, guided viewers through lesser-known hidden spots within the museum. Among these notable places is a massive lift, which remains a favorite among participants in children's programs. According to Kadi Polli, the museum's director, many museum staff are also unaware of these hidden features, highlighting the sense of discovery that exists even within a well-frequented public space.

The Kumu lift, notable for its size, was the largest in the Baltics at the time of the museum's completion in 2006, capable of carrying up to 9.2 tons and 122 people. This particular design has garnered significant attention from visitors, particularly children, who often mention it as their favorite part of the museum during feedback sessions after activities. This reflects the unique blend of functionality and interactive engagement that the museum offers to its youthful audience.

Additionally, Vahter showcased an underground pool located beneath the museum's parking area, which holds firefighting water ready for emergencies before fire trucks arrive. With a capacity of around 400 cubic meters, the pool serves as a crucial safety feature, illustrating Kumu's commitment to ensuring visitor safety while maintaining a degree of secrecy behind its structural elements. Such features not only enhance the visitor experience but also emphasize the museum's thoughtful planning regarding safety and engagement in the arts.
