while the Lakeside Exhibition Hall (also known as the North Exhibition Hall) was built below Mall C between the Cuyahoga County Courthouse and Cleveland City Hall. The seating capacity of the main auditorium, including the main floor and the U-shaped balcony, was eventually reduced to about 10,000. Music Hall seats 3,000, and the Little Theater 600. 1964 alterations In 1964, the city constructed a new underground convention center. The ballroom/exhibition space below Mall B was demolished and a much larger "Great Hall" (the convention center) built in its place. A tunnel was constructed below Lakeside Avenue to connect the new "Great Hall" to the Lakeside Exhibition Hall. On the west side of Public Auditorium, a four-story (one source says three-and-a-half story) modern glass and metal entrance pavilion added new lobby space for both buildings. 1987 renovations From 1983 to 1987, the convention center and Public Auditorium were both extensively renovated. The Exhibition Hall below Public Auditorium was radically changed, with a lobby/ballroom created out of former service space at the north end of the hall. A stone staircase was built in this area to connect the space to the hall above. This area could accommodate up to 2,000 people. The rest of the old Exhibition Hall was turned into 15 meeting rooms (ranging in size from 10 to 700 seats), office space, a cocktail lounge, and a piano bar arranged around a central block. A corridor hugged the exterior wall of the old hall, providing access to the meeting rooms. This corridor had decorative stone panels on one side and painted wood on the other, and was lined with sturdy chair upholstered in luggage fabric. The old asphalt floor was covered with concrete, and then tiled and carpeted. Cove lighting lit the corridor and meeting rooms. The Lakeside Exhibition Hall was converted into a ballroom with kitchen, and the north wall of the hall torn out and replaced with a glass curtain wall that had views of Lake Erie. The bathrooms in Public Auditorium were renovated to make them accessible as well as modern, and all public spaces in Public Auditorium were retiled, repainted, and replastered, while furniture received new upholstery. The north terrace was rebuilt in four different colors of granite. New taxicab stands were built at each end of Public Auditorium, and small gardens placed at each end of each taxi stand. The overall decorating scheme featured colors
