Coit Tower
Coit Tower
Historical landmark
14 mins
Coit Tower, a slender white concrete column rising from the top of Telegraph Hill, has been an emblem of San Francisco’s skyline since its completion in 1933, a welcoming beacon to visitors and residents alike. Its observation deck, reached by elevator (tickets can be purchased in the gift shop), provides 360-degree views of the city and bay, including the Golden Gate and Bay bridges. The simple fluted tower is named for Lillie Hitchcock Coit, a wealthy eccentric and patron of the city’s firefighters. Coit died in 1929, leaving a substantial bequest “for the purpose of adding to the beauty of the city I have always loved.” The funds were used to build both the tower and a monument to Coit’s beloved volunteer firefighters, in nearby Washington Square. The tower was designed by the firm of Arthur Brown, Jr., architect of San Francisco’s City Hall. Contrary to popular belief, Coit Tower was not designed to resemble a firehose nozzle.

Serafina SF
Serafina SF
San Francisco
Against all odds, we have opened up our newest restaurant, Serafina, This little gem of a restaurant, perched on top of Nob Hill, has truly been a labor of love, as we were set to open at the end of February, and then had to do so during the ensuing pandemic....We are so excited about Serafina, which has been a concept in the making for many years for us. Serafina was Maurizio’s grandmother, and the name of her eponymous restaurant in the heart of Trastevere (Rome), where Maurizio first began making pizzas at the age of 14. She was a tough woman and wonderful chef.. an inspiration for his love of cooking then, and inspiration of how he is determined to persevere despite the difficult circumstances of today. We hope to create a warm, elegant space where neighbors and friends can come together. We have an amazing team with our partner Giuseppe Terminiello, the co-owner of Piccolo Forno with us (we also own Ideale, in North Beach as well), and Umberto Cannarsa, an accomplished and incredibly talented chef from Rome, who had his own successful restaurants there.
