There two popular place to observe Tallinn. One is in the middle of Old Town (I’ll post photos from there in the note about night Tallinn), another is on the wall which is a border of Old Town.
This is the way up to obsevation. Actually you can go in the Old Town, using the other way, and it won’t need to climb up.
During climbing you can see something like this.
Message for tourists like me.
The view from the observation.
You can feed seagulls there.
Seagull and the view.
