I would be happy to undertake a write-up on the Ciudadela complex (the Citadel). Question though: do the write-ups need to be in the form of articles to be included in the tour, or can homes that have been dedicated to that particular building/monument etc be included too? If the later, I'll turn my home into the Ciudadela complex and post the information there, otherwise I will submit the text to one of you patrons for posting as an article. No bother either way :D
