Watching the Ashes - it's made a link in my mind that when I was watching a Big Bash game, they mentioned something about a restaurant in Melbourne called Stalactites.
no nothing like that but you're in the ball park with "decoration" but most certainly not Christmas lights. I wonder if a flick through a decent dictionary will give the answer? I haven't looked myself tbh but I have formed the question on a literal definition.
Not a firework, or anything like. Decorative. Unusual in the UK outside of certain places of worship.
stalactite work, also called honeycomb work, Arabic al-ḥalīmāt al-ʿuliyā (“the overhang”), pendentive form of architectural ornamentation, resembling the geological formations called stalactites. This type of ornamentation is characteristic of Islamic architecture and decoration. It consists of a series of little niches, bracketed out one above the other, or of projecting prismatic forms in rows and tiers that are connected at their upper ends by miniature squinch arches. Its infinite varieties may be classified into three groups, the first consisting of those basically niche shaped, in which the concave curve is the most important feature; the second group includes those in which the vertical edges between the niches are the most important feature; the last group consists of elaborately intersecting, miniature arches. The first two groups occur commonly in Syrian, Moorish, and Turkish work and, in their simpler forms, in Persia; the last group is typically Persian and is also found in Mughal work in India ??
Didn't help I mistyped the last clue "except in places..." well done. No idea who that is but I feel as if I should know.
