International Exhibition and Congress Centre. Inside the park, stands the Villa Erba International Exhibition and Congress Centre, a glass and steel construction that is inspired by the design of the old greenhouses of the lake: a perfect balance between history, elegance and innovation. This extraordinary building, with an overall area of over 10,000 square metres, consists of a circular pavilion and three adjacent wings: Lario, Cernobbio and Regina, able to host more than 500 stands, but also 28 independent meeting rooms with capacity ranging from 50 to 1,500 seats.
