This isn't exactly an empty lot - we'll call it a series of stacked lots over a retail cavern - but it's not put to very good use, either. On the north side of Chemeketa street between Liberty and Commercial you can see the corner of the alley in each photo. On the alley today are Carl's Cuisine, the elevator, and J.C. Penny. Presumably the Argo was demolished when the parking garage went up (but we haven't confirmed this).
On the south side of Chemeketa, the parking garage wiped out the Eldridge Block. The very south-most portion remains today as the home of Greenbaum's, but before the garage the block was three times as big, and extended to the corner where the shoe shop is today. You can see it here and here. And here is one a little later in 1954 that shows the whole Eldridge block with Greenbaum's.

Another of the empty lots is the one behind TJ Maxx and Rite-Aid downtown. Next to TJ Maxx is a curious building, a gabled garage with two mostly parabolic-y arches on the side facing Marion Street. You can just see it behind the man's head in the first image.

There's not a whole lot written and easily accessible on the Busick Market in this location, but the name remains in the Busick Court restaurant on Court Street. There was more than one Busick Market location, and we don't know the relation between them all.
So here are three ways the old downtown used to have a lot more character. We drink a toast to lost charm and buildings lost!
