I think that the main reason to visit Salamina is to just wander around the streets and enjoy the typical 'paisa' architecture. Salamina is one of the oldest paisa towns in the region, and due to its isolation has retained a small-town paisa feel, as well as the architecture.
Many of the houses and building have ornately decorated wooden doors, window shutters and balconies.
The only church in Salamina is on the north side of the main plaza. It has an ornately decorated wooden interior. It was built between 1865 and 1875.
The main plaza in Salamina is the centre of all activity in the town, which is not saying much considering just how sleepy/quiet of a town it is. There is a church on the north side and the 'alcaldia' (mayors office) on the east side. On the south and west sides are restaurants and a hospedaje, where I stayed.
The plaza itself is much more park like than most 'main plazas' in Colombia. It has many trees and a fountain the middle, as well as a gazebo on the south-west side.
There is only one bus company that services Salamina, they have an office on carrera 6, a few blocks south from the main plaza. As Salamina is a small place, there are no buses originating or terminating here, so you must show up at the office and wait for the next bus to come through town.
Salamina is along the Medellin-Manizales route, with buses going in both directions. The bus company in Salamina service buses from Medellin in the north down to Armenia in the south, passing through Manizales & Peireira along the way, as well as many small villages. To get to any destination outside of this route, you will have to transfer somewhere along the way.
While wandering around the city a little I came across the cemetary. Then as I got closer, I noticed what was above the main gate, a skull and crossbones symbol! I have never really been in many cemetaries, so I don't know if this is normal, but I found this somehow a kind of odd thing to have on a cemetary...
