have done as Joe suggested and am now chosing colours for different types of structures before placing symbols.

Thanks @Royal Scribe. I'm after walls specificaly (sorry about spelling, just surfacing after a very long sleep). I'm trying to create a modern-ish city which has a very old part complete with a small ancient wall. I don't know where in the world you are but I'm in the UK and many very old cities have the remnants of the old stone city walls merged with the modern houses etc. I'll look at Cities and Dungeons of Schley (never thought to look at Dungeons) as well as City Ruins.

EDIT SS5 doesn't have broken walls, just nice neat complete ones.

after about 10 failures I've started a map using the Jon Roberts City template for the background and water (and walls & towers and bevelled high ground) before switching to SS5 for houses. I was startled to find that my limited number of annuals (going back only to 2022-ish) doesn't feature many castles, never mind castles that will 'play nice' with other symbol sets.

Here's my first attempt at a castle mound. Incidentally it is the first attempt (that worked) at using connecting symbols. It happened by accident and when I tried with the SS5 walls it was a dismal failure. Yes I know the bevel is way too light, but I'm working on it.

Just to let you know I'm ready to start Thyra, @Monsen .
