The Schloss’s central courtyard is surrounded by Gothic and Renaissance buildings so elaborate they often elicit gasps from visitors, as do the breathtaking views of the Altstadt and the Neckar Valley from the terrace (through the archway at the bottom of the courtyard). The terrace’s benches are perfect for a picnic.
The only way to see the less-than-scintillating interior of the Friedrichsbau , rebuilt (or, more accurately, built) a century ago, is on a guided tour. Psalm 118 is inscribed on the façade in Hebrew and Latin.
