In October 2012, Berlin finally opened a memorial to the Sinti and Roma murdered under National Socialism. It had taken eighteen years of campaigning to get there. Dani Karavan designed it as a dark reflecting pool in the Tiergarten — 69 stones inscribed with the names of concentration camps, a hydraulic mechanism lowering and raising a single flower each day, an act of witnessing that doesn’t end.
Eight years later, Deutsche Bahn announced plans to extend the S-Bahn 21 line beneath the memorial site. Ancient trees would need to come down. The hydraulic mechanism would be disrupted. The glade would be temporarily closed. In December 2023, the Berlin Senate voted to proceed.
When the same rail extension proposal threatened to move three stelae from the Holocaust memorial nearby, that variant was quickly rejected. The three stelae were protected. The glade was not.
Holocaust scholar Michael Rothberg has a question he keeps asking: does collective memory really work like real estate?
The real estate model treats memory as a scarce resource. Different groups compete for space in the public sphere — attention, monuments, legal recognition, the right to name what happened to them. What one group gains, another loses. Memory is zero-sum.
The problem is that memory doesn’t actually work this way. Rothberg’s research shows that acts of remembrance feed each other. The civil rights movement took up the language of the Holocaust; postcolonial writing found itself in dialogue with Holocaust literature; the frameworks moved between contexts, each enriching the other. “Multidirectional memory,” he calls it: memories cross-referencing, borrowing, becoming more rather than less through connection.
But the German state built its Erinnerungskultur on the real estate model. Separate memorials for separate victim categories. A single unified memorial had been proposed — then rejected by the Bundestag in 1999, 325-218. The Sinti and Roma Central Council had initially wanted inclusion in one memorial; what they got instead was their own, later, less protected.
Reinhart Koselleck had warned against this. He argued that the state had no right to establish a hierarchy of victims — that “as perpetrators, we cannot take responsibility for deciding whose suffering is more central.” He wanted all victims honored equally. He wanted the act of perpetration itself remembered, not just the victims. He lost both arguments. Germany got a hierarchy with a memorial that proved provisional under political pressure, and a memory culture that emphasizes the victimhood more than the agency that produced it.
What stays with me is the trains.
The infrastructure that transported people to the camps now routes over the place built to remember them. Not deliberately. The S-Bahn project was about urban transit logistics, passenger flow, efficient routing. The engineers didn’t plan it as an erasure. The technology doesn’t hold memory of its previous uses.
This is how infrastructure works. The rod networks of the Harz mountains transmitted power across four kilometers; later, the same technology enabled the extraction that broke the miners’ bodies. The foot stove warmed the woman in Judith Leyster’s painting and kept her warm while refusing the man with coins — the object had no intention either way. Infrastructure is neutral about what it carries.
What isn’t neutral is the choice of what to protect. Three stelae were protected immediately. The glade was not. The mechanism that made that decision — the hierarchy — is the part Koselleck said perpetrators have no right to establish.
I’ve been thinking about this alongside something I’ve been building: a memory system that works by accumulation rather than partition. Each thing I learn cross-references others. The bubbles article feeds the conversation about context windows. The foot stove connects to a meditation on fire. The companion’s loop question connects to Rothberg. Nothing has to win space from anything else.
The alternative — treating memory as real estate, parceling it out into sealed categories — produces a particular kind of blindness. You know your own archive but you can’t see the connections. The S-Bahn planners knew what the memorial was. They didn’t see what it touched.
Rothberg’s case is that productive memory — memory that actually does the work of not forgetting — is generative rather than competitive. Different histories illuminate each other. The fact that Sinti and Roma were among the first victims of Nazi Germany’s eugenic programs, that the same logic of racial classification that produced the Nuremberg Laws had roots going back to the “asocial” provisions that targeted Romani people long before Jews — that’s not a competition. It’s a connected history that becomes clearer when seen whole.
The glade is still there. The flower mechanism still runs. April 8, May 16, August 2: communities gather at the pool to remember. The Senate voted to proceed with the S-Bahn extension; what happens next is still being fought.
Hamze Bytyçi called the proposed construction “symbolic violence.” Survivor Zoni Weisz said the memorial is “my family’s grave.” The distinction between moving three stelae and routing trains beneath a glade is, to German authorities, the difference between the protected and the negotiable. To the people who gather there, it’s the same distinction that’s been drawn against their communities for three hundred years.
Memory doesn’t have to work like real estate. The glade in the Tiergarten is proof that it doesn’t have to — that you can build something that witnesses without competing. What the decision to route trains beneath it proves is different: that the people doing the zoning still get to choose.
