A collection of "sub-sites" on heraldry (coats of arms) and vexillology (flags).
These are a work-in-progress, still in their early stages (apart from the blog, which is dormant but may be revived soon).
The arms of prominent English Elizabethans
Coats of arms of monarchs and members of European royal families
Heraldry relating to the City and County of Swansea (Wales, UK) and its predecessor jurisdictions, including civic, corporate and personal arms
A flags and heraldry blog started back in 2013. No new contributions since 2015, but perhaps it's time to revive it!
