The new site was overlooked to the north and west by a steep promontory known as Coogan's Bluff.
Because of its elevation, fans frequently watched games from the Bluff without buying tickets.
The ballpark itself was in bottomland known as Coogan's Hollow.
The grandstand had a conventional curve around the infield, but the shape of the property made the center field area actually closer than left center or right center.
This was not much of an issue in the "dead ball era" of baseball.
The land remained in the Coogan estate, and the Giants were renters for their entire time at Polo Grounds II, III and IV.
The Brooklyn Dodgers played a pair of home series at this ballpark in late July and early August 1890.

After the National League version of the New York Giants moved into Polo Grounds III in 1891, Polo Grounds II was sub-leased to the Manhattan Athletic Club and was referred to ever after as Manhattan Field.
It was converted for other sports such as football and track-and-field.
It still existed as a structure for nearly 20 more years.
Babe Ruth's first home run as a Yankee, on May 1, 1920, was characterized by The New York Times reporter as a "sockdolager" (i.e. a decisive blow), and was described as traveling "over the right field grand stand into Manhattan Field."
Bill Jenkinson's modern research indicates the ball traveled about 500 feet (150 m) in total, after clearing the Polo Grounds double decked right field stand.
Manhattan Field continued to be an occasional site for amateur sports reported in local newspapers as late as spring of 1942.
In June 1948, the Giants again leased the Manhattan Field property, and had it paved over to serve as a parking lot for the Polo Grounds.
