The Luminarium — a giant inflatable maze of light — is now being set up outside the University of Lincoln.
The walk-in structure will be open from April 5 to April 8 between 1pm and 7pm. Entry costs £4 on the day (free for babies under 18 months).
There will also be child-free sessions (over 16s) on Thursday, April 5 and Friday, April 6 between 5.30pm and 7pm.
The Luminarium was brought to the city by the Lincoln Performing Arts Centre (LPAC) to celebrate its 10th anniversary.
