The handsome, carved sea-green exterior of the post office, dating from 1917, is hard to miss among the bland buildings surrounding it. Stamp collectors should stop at the Museo Filatélico (Philatelic Museum. 223-6918), to the left as you face the stamp windows, for its display of first-day stamp issues. Early-20th-century telegraphs and telephones are also on display. The museum is open weekdays 8-5; admission is free. From the second-floor balcony you can see the loading of apartados (post-office boxes) going on below: Ticos (which is what Costa Ricans call themselves) covet these hard-to-get boxes, as the city's lack of street addresses makes mail delivery a challenge.
