The answer is:
PIGPEN PUZZLE
First consider the chain of symbols in the top 'header row'...
These are the grid-spaces of the pigpen cipher in order. i.e. The rows of a 9-square octothorpe-shaped grid (used for letters A-R), and the sectors of the 4-triangle cross-shaped grid (letters S-Z):
You can see this more clearly if you divide the symbol chain like so:
Now consider the circles and crossed-circles beneath...
In each case, (i) the horizontal position of the circle shows which part of the Pigpen cipher grid to use (by seeing which of the header row symbols it falls directly beneath), and (ii) an uncrossed circle indicates we are supposed to use the 'dotted' Pigpen grids, while a crossed-circle means we do not need a dot.
The first letter encoded here is therefore a 'P', being in the column below the 'bottom-left grid corner' symbol, and with a dot (indicated by the circle character).
If we repeat this process for all the circles and crossed-circles...
...and read off the corresponding letters from top to bottom of the diagram, we get the following solution message:
