This photo takes us back to Pasadena in around 1898. We’re looking north up Fair Oaks Ave from the southwest corner of Dayton St. On the left we can see the Acme Hotel (surely they could have come up with a more imaginative name than that?) I’d love to see a photo of the front of the hotel because their corner-facing turret looks like it was quite picturesque. From the horse-carriage tracks along the street, it appears that Fair Oaks Ave wasn’t paved over, but it was wide enough to accommodate lots of horse-drawn vehicles, which was probably handy when the weather turned wet and muddy.
Roughly the same view in February 2021:
A familiar corner to me, but not in that top picture! We sat there several years in a row for the Doo Dah parade back in the day.
That dome visible on the right of the current photo is on the Green Hotel, which is a very cool building. It was built in 1893, so, unless it was built in stages, your top photo is probably earlier than 1898.
