From the Halifax Railway station entrance, on looking the crossroads, on the left on the pavement, take the steps going down to the Eureka! Children's Museum. Further down the steps leads to underneath the railway station itself.
Go down the first flight of steps and turn right immediately. This leads onto a second flight of stairs which lead onto the grounds of the Eureka! childrens museum. Once down the steps on to Eureka!, head left on towards the 1855 Building. The entrance is at the centre of the building and can be entered via the two large black doors.
