LAS VEGAS (AP) — The Tropicana Las Vegas has been a familiar landmark in a city known for constant reinvention since its grand opening in April 1957. Now it’s a jewel of Sin City’s past. The Strip’s third-oldest casino closed its doors for good on Tuesday. And demolition is slated for October to make room for a $1.5 billion Major League Baseball stadium. The decades that followed the Tropicana’s debut 67 years ago this week were filled with colorful events. Even in its sleepier years amid the boom in Las Vegas Strip megaresorts, it remained a landmark for its vintage Vegas lore, showing up as a pop culture reference in movies and TV shows. (Photo: AP)
