The Nuovi Uffizi (New Uffizi) renovation project which started in 1989 was progressing well in 2015 to 2017.[9] It was intended to modernize all of the halls and more than double the display space. As well, a new exit was planned and the lighting, air conditioning and security systems were updated. During construction, the museum remained open, although rooms were closed as necessary with the artwork temporarily moved to another location.[10] For example, the Botticelli rooms and two others with early Renaissance paintings were closed for 15 months but reopened in October 2016.[11]
