After close to 17 years, Lindt will quit its flagship Martin Place store.
The 264 square metre space on the ground floor of #53, at the south west corner of Phillip Street, was the scene of a high-profile terrorist siege in 2014.
Three people, including instigator Man Monis, lost their lives.
Lindt said factors affecting foot traffic, including COVID and disruption caused by construction projects, swayed its decision not to renew its lease beyond this month.
It still operates out of five metropolitan locations including Cockle Bay.
In March, Channel Seven announced it would vacate its ground floor Martin Pl tenancy, opposite Lindt, also after 17 years.
