Semiquincentennial = 250th birthday. It will happen in 2026.
Here is a taste of an article at Philly.com on the preparations:
One hundred years after the Founding Fathers signed the Declaration in Independence Hall, Philadelphia threw a crowd-pleasing Centennial Exhibition, which promoted the city’s fast-growing factories and put Fairmount Park on the map.
For the 150th, we hosted the Sesquicentennial. The “world’s fair” was a bust; but it left us with the city’s top modern attraction, the South Philly stadium district. And the Ben Franklin Bridge.
The 1976 Bicentennial brought us All-Star games and the Final Four. The public party was a bust; but the energy that went into clearing Independence Mall for it helped make Center City living fashionable again.
Now, a national group led by Philadelphians has been charged — by Congress and President Trump — with organizing projects to mark 250 years of American independence, in 2026. There’s time to plan a big Philly party with a purpose, and maybe to build useful, lasting improvements. If we don’t blow it.
It’s the “Semiquincentennial,” according to the federal law licensing the celebration, signed by President Barack Obama in 2016. (A quincentennial marks 500 years; a semi-quin is half as much.)
“We need a new name. I’ve been saying ‘Two-fiftieth,’ ” says Dan DiLella, the suburban Philly developer who will chair the United States Semiquincentennial Commission, which holds its first informal meeting, to be convened at Independence Hall, later this week.
