Once the place where foreigners had to go to phone home, Central Telegraph is a blocky, early constructivist building that's one block up Tverskaya ulitsa from Red Square. You can still make phone calls abroad here, as well as buy stamps, send a fax, or use the Internet—but mainly, Central Telegraph is a sight just worth a quick look from the outside now. The striking semicircular entrance is adorned with a huge digital clock and a large and constantly revolving lit-up
globe. Inside are currency-exchange counters, a pharmacy, a coffee shop, and ATMs in the lobby, plus the main post office.
