As we go further, we will approach the gunpowder laboratory built in 1868. It was used for preparation of gunpowder, analyses of explosives and armouring missiles. Currently there is an exposition of armour. In order to see it, you have to walk downwards by stairs or slideways. It is worth halting in a corner of the bastion. Here we can see the Niegocin lake. Moreover, there are well preserved cannon posts, i.e. artillery posts over the laboratory.
