Though it is best known for sinking on its maiden voyage, the RMS Titanic was also one of the most magnificent boats ever built. While there were passengers from all walks of life on board, the opulence of the boat’s interior is almost as legendary as its sinking. From a swimming pool and dog kennels to massive dinners and the magnificent grand staircase, first-class passengers had access to everything, according to ThoughtCo.

Common sense would dictate that the Titanic cost a pretty penny — which of course, it did. According to History, the cost of the RMS Titanic is an estimated $7.5 million, equivalent to about $200 million today. The astronomical cost associated with the building of this boat would lead you to hope it would literally be indestructible. Despite all the labor, time, and money put into it, the Titanic never made it past its maiden voyage.
