Fagan died of cancer in 1969, but the park lives on, cared for by others.
It was named an official city park in 1976.

The small circle has featured many unusual items through the decades, including a swimming pool for butterflies—complete with diving board—a horseshoe, a fragment of the Journal building, and a miniature Ferris wheel, which was delivered by a full-size crane.

On St. Patrick's Day, 2001, the park was visited by a tiny leprechaun leaning against his pot of gold and children's drawings of four-leaf clovers and leprechauns.
The park continues to be the site of St. Patrick's Day festivities.
The events held here include concerts by Clan Macleay Pipe Band, picnics, and rose plantings by the Junior Rose Festival Court.

In February 2006, the park was temporarily relocated during road construction to a planter outside the World Trade Center Portland, about 80 feet (24 m) from its permanent location.
It was returned to its home—now named SW Naito Parkway—on March 16, 2007, in true St. Patrick's Day style with the Royal Rosarians, bagpipers, and the Fagan family, including Dick's widow, Katherine, in attendance.
The legend lives on in the Fagan family.
One of Fagan's sons, Pat Fagan, lives in Gladstone and has enjoyed sharing the park with his own son. "
He loves it," Pat Fagan said. "
It's still the largest leprechaun colony west of Ireland."

In December 2011, plastic army men figures and small signs were placed in Mill Ends as a tongue-in-cheek flash mob demonstration for Occupy Portland.
One man, Cameron Scott Whitten, was arrested after he was asked by police to move from the sidewalk and refused.

In March 2013, the park's tree was stolen.
Officials planted a replacement tree, and one day later, a passerby found what appeared to be the stolen tree lying next to the new one.

The next month, officials from Burntwood, England, complained to Guinness, claiming that Mill Ends was not large enough to be a park and that Prince's Park, smallest in the UK, should hold the world record since it "has a fence around it" among other features.
In response, volunteers erected a fence (several inches tall) around and stationed an "armed guard" in the park.

The park has previously contained a tiny Ferris wheel which was "delivered by a normal-sized crane."

In 2018, Portland Parks & Recreation installed a miniaturized park sign and planted miniature roses.

In December 2019, the tree was cut down by an unknown vandal.
However, the tree was soon replaced.
