A Textual Inversion Style Embedding trained on a beautiful late-medieval town archway scene. You can expect to get chaotic red brick/stone and wooden buildings, with floral accents, and a golden hue in your images by calling Style-Renaissance in the positive prompt, and if you want to temper the effect, also call Style-Renaissance-neg in the negative prompt.

If you'd like the effect to come through stronger (some models need it), try bumping up the emphasis on Style-Renaissance - see the images below. Mostly, I find you'll need to reduce the strength of Style-Renaissance - it comes through pretty strongly. Move it to the end of your prompt, or tone it down with weighting.
