The Cincinnati Observatory, the oldest operating observatory in the country, is found in (where else?) Mount Lookout. The stately domed structure — where the National Weather Service was founded —opens to the public on Thursday and Friday nights for free peeks at the sky (cloud cover permitting). The observatory is also open one Saturday night per month. Come check out Saturn, Mars and the odd asteroid in this National Historic Landmark. 3489 Observatory Place, Mount Lookout, (513) 321–5186 or www. cincinnatiobservatory.org.

The tomb of President William Henry Harrison is an amazing — and often overlooked — piece of history. The tomb is actually a monument, an obelisk of Bedford limestone with marble entranceway that rises 60 feet atop a hill. Visitors are also treated to an amazing panorama of the river and Ohio River valley. Cliff Road west of U.S. Highway 50, North Bend. Open all year during daylight hours. Free. No phone (duh).

Summer is a great time to sign up for Communiversity, the UC program that may well offer the town’s most lively and fun courses. Topics vary from “Celtic Art and Ornaments” (taught by Celtic artist Cyndi Matyi) and “The Joy of Soy Cooking” all the way to “Rock Climbing for Beginners.” The non-credit courses are held at such far-flung locations as Music Hall, Devou Park, art galleries, even Sharon Woods Golf Course. Whether you’re looking to indulge in culinary arts, gardening, theater, dance, painting or whatever, this could be the class for you.Class locations and costs vary, (513) 556–6932 or www.uc.edu/ace/commu.
