Stephan Balliet, 28, is accused of trying to storm a synagogue filled with worshippers in the attack on October 9th, 2019 during Yom Kippur, the holiest day in the Jewish calendar.
After failing to break down the door, the attacker shot dead a female passer-by and a man at a kebab shop instead.
“The attack on the synagogue in Halle was one of the most repulsive anti-Semitic acts since World War II,” prosecutor Kai Lohse told a court in Magdeburg.
Lohse said Balliet had acted on the basis of a “racist, xenophobic and anti-Semitic ideology” to carry out an attack against not only those he killed but “Jewish life in Germany as a whole”.
The events that unfolded were like a “nightmare”, he added.
“At the end of this nightmare, the perpetrator murdered two people and injured and traumatised numerous others.”
During the trial, Balliet had insisted to the court that “attacking the synagogue was not a mistake, they are my enemies”.
He has been charged with two counts of murder and multiple counts of attempted murder in a case that has deeply rattled the country and fuelled alarm about rising right-wing extremism and anti-Jewish violence, 75 years after the end of the Nazi era.
Following the public prosecutor's summary, lawyers of co-plaintiffs will in turn sum up their case.
The defence will then make its last statement before the court hands down a verdict, likely in December.
The government's point man against anti-Semitism, Felix Klein, called the trial “a good opportunity to bring about debate in society about anti-Semitism”.
Anti-Semitic crimes have risen steadily in Germany in recent years, with 2,032 offences recorded in 2019, up 13 percent on the previous year.
