The zone definition (that piece of code with the blueish remark at the left) should be put inside your db/pre-re or re/map_zone_db.conf (sample, renewal one).
Also, that alone mapflag should be in a new section of the map zone, called mapflag. Check that file for more examples.
As a side note, maybe you'd prefer to have that zone inherit GvG2 zone because that's a WoE SE castle.
P.S.: It'd be better if you also explained your issue instead of just throwing out the images, this way we don't have to figure out the problem.
