Why is "House-shaped shrine" trending?

Wikipedia Overview

House-shaped shrine are early medieval portable metal reliquaries formed in the shape of the roof of a rectangular building. They originate from both Ireland and Scotland and mostly date from the 8th or 9th centuries. Typical example consist of a wooden core covered with silver and copper alloy plates, and were built to hold relics of saints or martyrs from the early Church era; a number held corporeal remains when found in the modern period, presumably they were parts of the saint's body. Others, including the Breac Maodhóg, held manuscripts associated with the commemorated saint. Like many Insular shrines, they were heavily reworked and embellished in the centuries following their initial construction, often with metal adornments or figures influenced by Romanesque sculpture.
