During those mad years of LOTR I built a large collection of GW fantasy 28mm figures and accessories.
But the larger models- the fortressses and cities, for instances - had to be scratchbuilt.
Here it goes my approach to Helms Deep, using mainly styrofoam.
The door is one of the few elements made of wood and it opens with the help of some pegs.
The broken statues were made of Green Stuff.
The stairs are plastic glued to the styrofoam. This model gave me a big pleasure to build as you can work styrofoam quickly and with nice results. I tryed to use the same techniques I saw in GW magazines of the days ın which LOTR was rocking copying shamelessly those big modellers and painters they have.
