Final answer:
The current name of the Titanic's last port of call is Cobh, formerly known as Queenstown, located in County Cork, Ireland.
Step-by-step explanation:
The current name of the Titanic’s last stop before its fateful journey across the Atlantic is Cobh, which was formerly known as Queenstown. Cobh is located in County Cork, Ireland, and it was the final port of call for the RMS Titanic in 1912 before she set out on her maiden voyage. At that time, it was known as Queenstown, a name it carried through the period when Ireland was part of the United Kingdom. The town of Cobh is steeped in maritime history and today serves as a significant point of interest for those who are fascinated by the storied past of the Titanic.
