A theatre that outlived the empire by becoming a fortress, then a palace, then an address.

Chronology

Mid-1st century BCE — Julius Caesar begins the theatre, acquiring and demolishing to make room for it. Structural impact: the site is cleared and the footprint fixed. What you see today: the curve of the plan, which has not moved since.
c. 17 BCE — Augustus resumes and completes the work. Structural impact: the arcaded masonry shell is finished — a theatre standing free on flat ground rather than cut into a hillside. What you see today: the two surviving tiers of travertine arcades.
Between 13 and 11 BCE — dedicated, and named for Marcellus, Augustus's nephew and son-in-law, who had died in 23 BCE. Wikipedia puts the inauguration at 12 BCE. Structural impact: none; the building is complete. What you see today: the name, which is all that survives of him here.
1st-3rd centuries CE — restorations under Vespasian and Alexander Severus. Structural impact: Roman-period repair keeps the fabric in use for three centuries. What you see today: masonry that has been patched since antiquity rather than left to fall.
Early Middle Ages — the theatre becomes a fortress, held by the Fabi and, from the end of the 11th century, by Pier Leoni and the Pierleoni. Structural impact: the arcades are given a reason to be maintained while the upper tier and the entire interior are quarried away. What you see today: exactly two tiers, and no auditorium.
13th century — the Savelli hold the structure. Structural impact: continued fortification and occupation. What you see today: the mass above the arcades, which is medieval before it is Renaissance.
16th century — the Orsini commission Baldassare Peruzzi to build a residence on top of the ancient ruins. Structural impact: a domestic facade of windows and cornices springs directly from the Ionic tier. What you see today: the seam — travertine arcades, a horizontal break, then plaster and shutters.
19th century — the street level has risen so far that almost half the ground floor sits below it. Structural impact: the building is half buried by its own city. What you see today: the depth of the excavated area, which is the measure of what was removed.
1930s — the municipality of Rome partly excavates and restores the monument, clearing the accumulated ground and the buildings around it. Structural impact: the lower arcade is freed and the surroundings demolished. What you see today: the open archaeological area, and the fact that you walk below the road to reach it.
