General William Jenkins Worth never visited Fort Worth. He actually died before the fort was ever established. He passed away from cholera in San Antonio a few months before. However, that is probably why the fort was named after him because of the fairly short amount of time between his passing and setting up of the fort.
The block bounded by 8th, Commerce, 9th, and Main was the home of the Metropolitan Hotel. It was built on the western half of the block in 1898 by Winfield Scott. It was doubled in size around 1905 to include the eastern half of the block. In 1938, it was sold to the Milner Hotel Corp. and remained in their hands until 1959. However, it was during this time that it became run down. The hotel closed in that year and was demolished for a parking lot. It was in that parking lot where John F. Kennedy appeared before the public on the day that he was assassinated. In the mid-1960's, the Moncrief family purchased the southeast corner of the block and built their office building on the site. In the late 1970's, with the restoration of the old Hotel Texas (Hilton) and construction of Continental Plaza (777 Main) planned, the City of Fort Worth purchased the remaining 3/4 of that block and 1/2 block to the west where Washer Bros. was located. The city built a 2 level underground parking garage that connected into the Hotel Texas with a city park on top. At that time, there was no place honoring General Worth, so they decided to name the green space after him.
This is why there is a concrete ramp going down off of Commerce and off of 8th Street. These ramps need to be in place to utilize the underground parking.
