Why is "Memorials and monuments to victims of the Titanic" trending?

Wikipedia Overview

Memorials and monuments to victims of the sinking of the RMS Titanic exist in a number of places around the world associated with Titanic, notably in Belfast, Liverpool and Southampton in the United Kingdom; Halifax, Nova Scotia in Canada; and New York City and Washington, D.C. in the United States. The largest single contingent of victims came from Southampton, the home of most of the crew, which consequently has the greatest number of memorials. Titanic was built in Belfast, Northern Ireland, and had a "guarantee party" of engineers from shipbuilders Harland and Wolff aboard all of whom were lost in the disaster and are commemorated by a prominent memorial in the city. Other contingents of engineers aboard the ship came from the maritime cities of Liverpool in England and Glasgow in Scotland, which erected their own memorials. Several prominent victims, such as Titanic's captain, were commemorated individually. Elsewhere, in the United States, Australia and Bulgaria, public memorials were erected to commemorate all the victims.
